What is 2,5-Di(HD)-3,6-di(5-broMothiophen)diketopyrrolopyrrole?

Description

3,6-bis(5-bromothiophen-2-yl)-2,5-bis(2-hexyldecyl)pyrrolo[3,4-c]pyrrole-1,4(2H,5H)-dione (DPP-HD-2ThBr) is a family member of?pyrrolopyrrole-dione (DPP). This monomer has been used for the synthesis of?PDPP3T, which is a low band-gap polymer semiconductor?commonly used?as i) a polymer donor material for OPV, and ii) hole-transport layer (HTL) for perovskite solar cells.

The Uses of 2,5-Di(HD)-3,6-di(5-broMothiophen)diketopyrrolopyrrole

DDP-Br₂ can be used in the fabrication of a variety of opto-electronic devices such as organic field effect transistors (OFETs), perovskite based solar cells, non-fullerene organic solar cells.

General Description

3,6-Bis(5-bromo-2-thienyl)-2,5-bis(2-hexyldecyl)-2,5-dihydro-pyrrolo[3,4-c]pyrrole-1,4-dione (DDP-Br₂) belongs to the series of diketopyrrolopyrrole (DPP) based materials which show hole or ambipolar transport behavior with mobilities of charge carriers in the range of 0.1-1 cm²V^-1 s^-1. It has an electron deficient core that forms a low LUMO energy level which facilitates better air-stability for n-type organic semiconductors.
