IDTTB6-2CHO, for the synthesis of low band gap non-fullerene acceptors

High purity monomer available online for fast, secure dispatch

IDTTB6-2CHO, CAS number 1878125-76-8, 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.
