Among the most widely used red light-emitting or photorefractive materials are 4H-pyran-4-ylidene or azobenzene fragment containing derivatives, which are conjugated in a system with electron acceptor and electron donor fragments. Synthesis of such compounds is simple and reactants are available. Therefore the main objective of our work was the synthesis and characterization of physical properties of D-p-A type molecular glasses, which in their molecules would also contain bulky trityloxyethyl- groups. The presence of trityloxyethyl- substituents in those molecules could ensure their ability to form good optical quality glassy transparent films from non-polar organic solvents. Various derivatives of 4H-pyran-4-ylidene and azobenzene with incorporated trityloxyethyl- groups in their molecules have been synthesized and their physical properties have been investigated. Obtained compounds form thin solid transparent films from non-polar organic solvents with technologically simple and non-expensive "spin-coating" approach. Synthesised compounds could be used in organic solid state lasers.
