Abstract
Synthesis of new asymmetric poly-π-conjugated amino derivatives of biphenyl and 3,5-dioxodibenzothiophene containing phenylethyl and fluorophenyl ethenyl fragments in the main chain of conjugation and cyclic fragments as the central chromophore was conducted. Due to the presence of alkylamine substituents, a bathochromic shift (by 15–25 nm) is observed for all the synthesized compounds in comparison with compounds that do not have alkylamine substituents. The compounds obtained are blue phosphorescent luminophores.
