Y6 (BTP-4F) is a highly conjugated organic semiconductor. It is composed of a fused thienothienopyrrolo-thienothienoindole (TTP-TTI) core base and 2-(5,6-difluoro-3-oxo-2,3-dihydro-1H-inden-1-ylidene)malononitrile (2FIC) end units. These 2FIC end units are believed to promote intermolecular interactions and enhance optical absorption.

BTPTT-4F (Y6) is a non-fullerene acceptor-donor-acceptor (A-D-A) type small molecular acceptor (SMA) characterized by its flexible alkyl chains and centrally fused ring structure. Featuring a ladder-type electron-deficient core, BTPTT-4F can be effectively blended with PM6, showcasing significant potential for enhancing the performance of organic photovoltaic applications. Its tailored optical properties and adjustable electronic energy levels contribute to improved thermal and photochemical stability, making it a promising candidate for next-generation high-performance organic solar cells.
