Novel organoboron compounds derived from thieno[3,2-b]thiophene and triphenylamine units for OLED devices

Abstract

Two novel D–A (donor–acceptor) and one D–A–D small molecules containing mesitylborane as an acceptor and triphenylamine as a donor, linked through a thieno[3,2-<italic>b</italic>]thiophene π-conjugated spacer, are synthesized and characterized.
