New Redox Stable Low Band Gap Conjugated Polymer Based on an EDOT−BODIPY−EDOT Repeat Unit

Abstract

The compound 4,4-difluoro-4-borata-3a-azonia-4a-aza-s-indacene, more commonly known as BODIPY, has enjoyed a high and rapidly escalating level of interest over the past decade.(1) This dye-type material, which can be likened to a porphyrin subunit, has been studied mainly in applications related to its strong absorption and fluorescence properties.(2, 3) Recent examples of the applications of BODIPY include biological tags with visible/near IR emission,(4, 5) mechanical rotors,(6) lasing,(7-9) dye sensitized solar cells,(10) electroluminescence (EL),(11) and electrogenerated chemiluminescence (ECL).
