BTP-4Cl-12 (CAS number 2447642-41-1), also known as Y7-BO or BO-4Cl, belongs to the highly efficient non-fullerene acceptor Y6 family. The only difference between BTP-4Cl-12 and Y7 is that BTP-4Cl-12 has larger butyloctyl alkyl chains that are attached to the pyrrole rings while Y7 has ethylhexyl alkyl chains at the clove of the U-shaped structure. Also, BTP-4Cl-12 has greater solubility so it has great advantage for solution processability and mass device production with environmentally benign solvents as active layer materials for organic polymer solar cells.
High efficient non-fullerene acceptor
With highly conjugated core
Improved solution processability
Owing to the branched ethylhexyl alkyl chains
