idttb6-2cho, 1878125-76-8
Chemical structure of 6,6,12,12-Tetrakis(4-hexylphenyl)-6,12-dihydrodithieno[2,3-d:2',3'-d']-s-indaceno[1,2-b:5,6-b']dithiophene-2,8-dicarboxaldehyde (IDTTB6-2CHO), CAS# 1878125-76-8.

Applications

IDTTB6-2CHO has a fused Indacenodithienothiophene (IDTT) core structure with extended conjugation to the hexylphenyl side chain with large steric hindrance and electron-rich properties. 

Electron-rich IDTT is one of the most important building blocks for the design and synthesis of low-bandgap non-fullerene acceptors (NFAs), such as ITIC and ITIC-2F which are among the earliest developed NFAs for highly efficient organic photovoltaic devices.
