The synthesis, structure, and properties of 5,6,11,12-tetraarylindeno[1,2-b]fluorenes and their applications as donors for organic photovoltaic devices

Abstract

Three new highly twisted 5,6,11,12-tetraarylindeno[1,2-<italic>b</italic>]fluorenes have been synthesized, characterized with X-ray analysis, and utilized as electron donors in organic photovoltaics.
