Molecular photoswitches have aroused widespread interest in recent years. Because of their unique photochromic characteristics, they have been widely used in molecular data storage, photopharmacology, optochemical genetics, materials science, and biomolecules among other areas. Over the past few decades, most research has been focused on azobenzenes, spiropyrans, diarylethenes, and stilbenes which are all characterized by photoisomerization. Among these molecules, diarylethenes attract an attention due to their photochemical properties and potential ability for various applications [1, 2]. They can undergo two main intramolecular reactions: photoisomerization between trans (E) and cis (Z) isomers, and protonation. Due to its properties derivatives of diarylethenes can be used in nonlinear optics, optoelectronics, phototics.
In this work we present synthesis of new chromophores based on styrylquinoline as promising materials for nonlinear optics.
