Despite recent progress in optical manipulation techniques of small objects such as laser tweezers and laser cooling, manipulation of nanoscale objects by radiation force is still challenging in nanotechnology. We also discuss our most recent theoretical results, such as those on manipulating nanoscale objects by projected light fields [3], size-selective manipulation of carbon nanotubes [4], and interparticle radiation-induced force which would be useful for manipulating the collective motion of nanoscale objects [5][6].

Strong fluorescence quenching for (ZnOEP)2Ph or (ZnOEP)3Ph2 is governed by competing processes of energy migration (EM) and photoinduced electron transfer (PET) to the extraligand (~0.9 ps). In the case of covalently bound electron acceptors (A) of a non-porphyrin nature (quinone, pyromellithimide), the strong shortening of the decay of the S1 state (quenching of fluorescence) of the dimer is the result of EM and PET processes of the extraligand (~0.9-1.7 ps), which are faster than the slower PET «dimer→A» (34-135 ps) in toluene at 295 K.

It was found that when this film is placed in water containing Co or Ni ions, QD luminescence occurs with an intensity proportional to the ion concentration in the solution. The data show that the diffusion of Co or Ni ions from an aqueous solution into a polymer film containing QD/PAN complexes results in the dissociation of these complexes, followed by the appearance of QD luminescence. It was found that polymer films with embedded QD/PAN complexes can be considered as a luminescent nanosensor.

When the film is placed in a water solution containing metal ions, they diffuse into the film and stimulate dissociation of the QD/PAN complexes. Since the luminescence is excited by optical radiation, the question arises of possible photodissociation of the sensor and its influence on parameters of the sensor's luminescence response. This information is important for determining the excitation light parameters necessary for sensor utilization for analytical applications.

In toluene solutions of PBC under the same conditions, only two photoproducts were observed - ВE with λmax = 600 nm and АКt with λmax = 500 nm. The nature of the solvent has a dominant influence on the number of photoproducts of PBC photolysis, the kinetics and mechanism of their bleaching reactions. The influence of substituents in the SA fragment of PBC molecules on the ratio of two photoprocesses and the lifetime of photoproducts is discussed.
ZINC)TETRAPHENYLPORPHYRIN-FULLERENE CHARGE-TRANSFER COMPLEXES
LITERATURE
The nonradiative relaxation of the dimer S1 state in self-assembled triads and pentads occurs within ∼1.6 ps with respect to τS=1.2 ns for individual dimer. Instead, fast EM and ET processes are followed by the effective population of the extra-ligand T1 state. Bimolecular rate constants for the extra-ligand T1 states that quench with O2 are reduced by 1.4-1.8 times those found for individual monomeric porphyrins.

Another - "bottom-up" - approach requires the creation and research of the various molecular systems capable of acting as signal conductors, switches, diodes, memory elements and also logic devices. Dependence of values of output signals on inputs is defined by the truth table of the logical (Boolean) function. The response can be different, and thus it is possible to do different logical operations using the same molecular system.

Based on the results, a full description of the oxygen movement in the protein matrix will be given and the kinetic mechanism of protein self-regulation of ligand binding will be discussed. Therefore, to answer the question of which photocatalysts are more active, one needs to know the spectral distribution of the quantum yield for the corresponding photoreaction. A qualitative explanation will be given based on a model that takes into account the spectral variation of the electron transfer pathways.

Our quantum chemical calculations confirm the existence of energetically favorable stacking dimers of Ade in water (see Table 1). All stable stacking conformers in aqueous solutions of Ade7 and Ade9 have the interplanar distance R Å.

Spectra of HCN/D2O and ND3/D2O ice mixed films with low (1:10) dopant/water ratios do not show any change in the acidic or basic properties of the pendant hydroxyl groups or surface oxygen atoms, but reveal a difference in the ratio between the concentrations of these sites compared to pure water ice. Co-adsorption of ozone with HCN in the dark does not lead to any noticeable spectral changes. However, the UV radiation of this system results in the appearance of new bands that reveal the formation of ozonolysis products.

Mineral templates can drive light-dependent processes that result in the formation of molecules of varying complexity. The energizing particles of the clay mineral, montmorillonite, were shown to catalyze the formation of pyrophosphate and phosphoanhydride bonds in the nucleotide coenzymes ATP and FAD. Thermolysis of amino acid mixtures results in the formation of abiogenic pigmented polymers (flavoproteinoids) which aggregate and form microspheres.

A “sandwich” structure is developed with a parallel (D13-1) and an antiparallel (D13-2) orientation of the short axes of the molecules that form a dimer. The calculations of rate constants of photophysical processes in dimers show that the formation of dimers significantly affects the energy level diagram of the excited electronic states of the monomer. In addition, the value of the rate constant of these non-radiative processes depends on the dimer structure.

The purpose of the presented work is to try to prevent destruction during recording and partial deletion during reading of information. To avoid the erasure of the recorded information, it is usually possible by means of matrices where the photochromic transformation is accompanied by changes which can be detected without destroying the written information. Therefore, reading through the Bragg reflection band, rather than an absorption maximum, will ensure the storage of written information without loss.

Photoinduced oxygen isotopic equilibration (POIE) 16O2 + 18O2 → 216O18O on TiO2-x was used to test the stability of surface defects in the reduced sample upon irradiation in an oxygen atmosphere and to test the photocatalytic activity in the absence of the reducing agent CO. was investigated. After the light is turned off, the reaction continues ("memory" effect) and R slowly drops to zero. During POIE, there were no changes in the total pressure, which indicates the invariance of the adsorption-desorption balance.
EFFECTS OF DONOR STRUCTURE ON TRIPLET ENERGY-TRANSFER FROM AMINES TO ALKENE IN SOLUTION
One of the most interesting manifestations of this interaction is associated with non-radiative photoprocesses - the energy transfer of electronic excitation between two chromophores. This theory allows you to determine the dependence of the energy transfer efficiency on the spectral-luminescence properties of the molecules of a donor and an acceptor. Overall, the results of the quantum-chemical approach to the research of the energy transfer process.

One of the most promising macromolecular compounds that contain photo-operated groups and are therefore able to convert light energy into chemical bond energy can be chalcone podanders. It has also been shown that the selectivity of photocycloaddition can be regulated by changing the template concentration and varying the light irradiation range. One of the main requirements for the molecules of efficient polymeric photostabilizers is highlighted to be the absence of two-photon processes, which are possible by efficient radiationless conversion, initiated by reversible adiabatic chemical reactions.

In this work, the photoozonolysis of chlorinated ethenes and hydrogen cyanide on/in ice films was investigated by FTIR spectroscopy at 77 – 200 K. To investigate the influence of water addition on the reaction mechanism, photoozonolysis of hydrogen cyanide in mixed HCN /H2O ice at 77 K has been investigated. It was found that adding water promotes faster HNCO formation during the photoozonolysis process.

In contrast to MgO3, CO adsorption on CaO pre-exposed to CO2 or SO2 is not accompanied by OH band perturbations, and adsorption of DMP does not lead to characteristic bands of protonated base molecules. For CaO degassed at 773 K or exposed to H2O at 300 K, the surface concentration of OH groups is much higher, but after adsorption of CO2 or SO2, the intensity of the high-frequency CO bands is lower than for the sample treated at 973 K. Thus assigning we the high-frequency CO band to molecules coordinately bound to surface cations whose electron-accepting ability is enhanced as a result of CO2 or SO2 adsorption.

Moreover, ellipsometric measurements show that the PhC films have birefringence in the substrate plane. The index axis Ng is directed along the crystal growth line, Nm lies in the plane of the film surface and is orthogonal to Ng. This phenomenon requires an adequate theoretical description and takes into account in the engineering of elements for photonics.

A particular contribution of these spectral components to the blue emission of a given solution depends on the chemical structure of the fullerene. The quantum-chemical calculations carried out in the study allowed to estimate the strength of intermolecular interaction in groups and to underline their origin of charge transfer. The observed enhancement of linear optical events is considered within the framework of the local broadening field model and is related to the resonance excitation of clusters which are spatially extended charge transfer complexes.
NANOPHOTONICS IN PRINTING AND PACKAGING
Electronic spectra of NPs are size-dependent due to quantum confinement effects, and the term quantum dot (QD) is widely used to designate them along the lines of other low-dimensional systems. The overlap of NP excitation profiles enables NPs with different emission wavelengths to be excited simultaneously. It was determined that the size of the NPs as well as the stoichiometric PE:NPs molar ratio are the crucial parameters, which determine the topology of the NPsPE complexes lying on a solid substrate.

Nanosized structures (nanoclusters, NCs and nanoparticles, NPs) of organic and inorganic materials are of interest for photophysics research and applications in organic solar cells. PCBM molecules (both electron acceptors and quenchers of polymer luminescence) form NCs during the polymer composition preparation process. Photophysical properties of metal NCs and NPs are of particular interest for use in organic solar cells [10].

We observed this gap in the spatial distribution of optical radiation from the fluorescent 1D photonic crystal formed by hologram written in the CaF2:Na crystal. The spatial frequency of the hologram was equal to 1/2 of the reciprocal wavelength of the luminescence band maximum corrected for the crystal refractive index. The optical scheme made it possible to detect the spatial distribution of the luminescence at CCD camera plane, which was parallel to the hologram plane.
