Abstract

Incorporation of acenaphtho[1,2-c]pyrrole units into the π-conjugated systems is very effective to get the narrow HOMO-LUMO gap materials, and the absorption spectra of π-conjugated polymers, porphyrins, and boron dipyrromethene dyes fused with acenaphthene rings are extensively red-shifted.
