Abstract

        Stilbenes and their derivatives form a multidisciplinary field that combines many important branches of chemistry, biology, and physics[1-3]. This field, for the time being, is under active investigation. Unique features of this class of compounds, including a combination of fluorescence, phosphorescence and photochrome properties, have long been a matter of great interest to researchers. Also due to their miscellaneous photophysical and photochemical properties, stilbene compounds can be used for many applications in materials science. Data on the photochemistry of stilbene compounds and their role in materials science eg . materials for lasers, nonlinear optical systems, photoconductive materials, and imaging and switching techniques, were reviewed [3-6].

          Specifically, recent years have seen the accumulation of new facts and ideas in the following areas: (1) stilbenes have proved to be convenient models (‘‘proving ground’’) for experimental and theoretical investigations of detailed mechanisms of photochemical and photophysical processes including photochromism and multiphonone phenomena; (2) stilbenes are used as dyes, brighteners, whiteners of paper and textile, and photobleachers;  (3) stilbene derivatives have been used as molecular probes and labels for investigation of dynamic properties of proteins and biomembranes; (4) stilbene and its combination with polymers and inorganic materials have been made a basis for numerous optical and measuring instruments, devices, and apparatuses for dye lasers, organic solid lasers, and scintillators, phosphorus, neutron, and radiation detectors, electrophotographic photoconductor and image-forming apparatus, and photochromic, light-transmitting, dichroic, electroluminescent nonlinear optic, and organic–inorganic hybrid multichromophoric optical limiting materials.   

In this poster we will  report results of NMR examination, theoretical studies  and properties of novel aminostilbene. These compounds may be applicable for obtaining new materials for both photoconductive imaging and switching techniques.
