IDTB6-2CHO, high purity monomer

For the synthesis of non-fullerene acceptors used in highly efficient organic solar cell devices

4,4,9,9-Tetrakis(4-hexylphenyl)-4,9-dihydro-s-indaceno[1,2-b:5,6-b']dithiophene-2,7-dicarbaldehyde (IDTB6-2CHO), is a derivative of indacenodithiophene (IDT) with extended conjugation to the hexylphenyl side chains. IDT derivatives are electron rich and used as building blocks for the synthesis of non-fullerene acceptors (NFAs) that are employed in highly efficient organic solar cells devices.

Fused IDT core of IDTB6-2CHO is believed to have the function of facilitating π-electron delocalization and improving intermolecular π–π stacking, thus to promote the intrinsic charge carrier mobility.
