popup.description1
The goal of this research is to create and thoroughly investigate novel polymers capable to react to external stimuli, along with the development of hybrid nanocomposites based on these polymers. Our focus lies in establishing the fundamental principles for the predictable control of photo, electrical, optical, and luminescent properties of both polymers and nanocomposites. Our approach encompasses both theoretical and experimental studies on polymers containing chromophore groups/fragments and metal-polymer complexes. This investigation aims to fulfil the requirements of photonics by producing efficient materials with high nonlinear optical coefficients and information store properties for use in non-destructive testing methods.

The development of new generation materials based on macromolecular systems with predictable photochemical, optical, and nonlinear optical properties is one of the most pressing problems of modern polymer chemistry. For this purpose, macromolecular design methods are used, in particular, intra-chain doping of polymeric materials by introducing certain photoactive monomer additives to the basic monomer during its polymerization or by introducing photoactive compounds and metal nanoparticles into the polymer matrix. Photoactive fragments introduced into the polymer chain can significantly expand the range of applications of the resulting materials, since phototransformations characteristic of chromophore-containing fragments lead to changes in a large number of macroscopic properties. And as a result, such polymers and nanocomposites can be used to create materials with a change in the refractive index, transmission of polarized light, reflection, light dispersion, polarization, charge transfer, changes in dielectric properties, production of reactive oxygen species under irradiation, etc. The aim of this work is to conduct comprehensive studies of new polymers and polymeric hybrid nanosystems capable of responding to irradiation and to develop fundamental principles for the predictable control of photo-, electro-, optical, luminescent, and biological properties of polymers and nanocomposites. To achieve this goal, the following tasks were solved: synthesis and study of new chromophore-containing model compounds, their monomers and polymer matrices to create new functionalized nanocomposites with the introduction of organic and inorganic compounds, study of their photophysical, photochemical and nonlinear optical properties.
