详情介绍：
COTIC-4F has a molecular configuration of A−D'−D−D'−A that is based on an electron rich internal core of cyclopentadithiophene (CPDT) as the central donor unit flanked with alkoxythienyl units, terminated with two 2-(5,6-difluoro-3-oxo-2,3-dihydro-1H-inden-1-ylidene)malononitrile (IC-2F) acceptor units.
COTIC-4F is a narrow bandgap n-type molecular semiconductors extending its absorption from 700 nm to near infrared range (about 1100 nm) with an optical bandgap of ~1.1 eV. COTIC-4F can be used as active layer material for near infrared (NIR) responsive organic solar cells (OSCs ) and organic photodetectors (OPDs ).
