central acceptor were made. The central acceptors were dicyanovinylidene and 1,3-diethylthiobarbituric acid derivatives of 2-indanone in the set of symmetrical dyes and dicyanovinylidene in unsymmetrical dyes. The different acceptors allowed the tuning of optoelectronic properties. All the new materials were soluble in variety of organic solvents, such as chloroform, toluene and chlorobenzene. With
