PCE11 Monomer, used to modify energy gap of polymer semiconducting materials

Free worldwide shipping on qualifying orders


4-7-bis(5-bromo-4-2-octyldodecylthiophen-2-yl)-5,6-difluorobenzo[c][1,2,5]-thiadiazole, also known as PCE11 monomer (CAS number 1504626-07-6), is a monomer with difluoro attached on benzothiadiazole unit which gives greater electron withdrawn ability to further modify the energy gap of the polymer semiconductor materials. Polymerised with 5,5'-bis(trimethylstannyl)-2,2'-thiophene, PCE11 monomer yields the polymer PffBT4T-2OD (PCE11) which has a power conversion efficiency over 10%.

PCE11 synthesis with 4-7-bis(5-bromo-4-2-octyldodecylthiophen-2-yl)-5,6-difluorobenzo[c][1,2,5]-thiadiazole and 2,5-bis(trimethylstannyl)thieno[3,2-b]thiophene
Synthesis of PCE11 with 4-7-bis(5-bromo-4-2-octyldodecylthiophen-2-yl)-5,6-difluorobenzo[c][1,2,5]-thiadiazole and 2,5-bis(trimethylstannyl)thieno[3,2-b]thiophene
