D18 (PCE18)
D18, narrow bandgap copolymer with high hole mobility
Higher degree of conjugation than DTBT
D18, also referred to as PCE18, is a narrow bandgap copolymer with a backbone alternating electron donating benzodithiophene (BDT) and electron accepting fused-ring dithienobenzothiadiazole (DTBT) units. With a larger molecular plane structure and higher degree of conjugation from the fused ring DTBT, D18 has a high hole mobility of 1.59 × 10-3 cm2 V-1 s-1.
