An alternating polymer (PBDTFC 10 DBT) with benzo[1,2-b:4,5-b′]dithiophene (BDT) as electron-rich unit and 4,7-bis(4-decylthiophen-2-yl)-5-fluorine-2,1,3-benzothiadiazole (FC 10 DBT) as electron-withdrawing unit was synthesized and characterized. PBDTFC 10 DBT showed similar absorption property with that of the counterpart polymer without fluorine atom (PBDTC 10 DBT)...
A new alternating polymer (PBDTFQx) with alkoxy-substituted benzo[1,2-b:4,5-b′]dithiophene (BDT) as donor and fluorine-functionalized quinoxaline derivative (FQx) as acceptor, was synthesized and characterized using NMR, UV–vis spectroscopy, thermogravimetric analyses (TGA), and cyclic voltammetry. Photovoltaic devices with the configuration of ITO/poly(3,4-ethylenedioxythiophene)-poly(styrenesulfonate)(PEDOT:PSS)/PBDTFQx:...
