PFBT4T-C5Si-25% (Si25) 文献： Alternating and random conjugated copolymers with a siloxane-terminated side chain for a repeating unit based on 5,6-difluoro[2,1,3]benzothiadiazole (FBT) and quarterthiophene (4T) were synthesized, among which side-chain random copolymers PFBT4T-C5Si-50% and PFBT4T-C5Si-25% with low contents of 50% and 25% siloxane-terminated side chains, respectively, in conjunction with alkyl side chains were found to be more suitable for optoelectronic applications due to good film-forming in solution processing. Grazing incidence X-ray diffraction (GIXD) indicated that the siloxane-terminated side chain could induce PFBT4T-C5Si-50% and PFBT4T-C5Si-25% with face-on orientations, giving high 3-D hole transport in neat films as supported by a high hole mobility up to 2.46 cm2 V−1 s−1 in field-effect transistors and an SCLC hole mobility up to 5.9 × 10−2 cm2 V−1 s−1 in hole-only devices. Fast SCLC hole and electron transports were seen for their bulk-heterojunction (BHJ) blend films with PC71BM as the acceptor, due to the retention of a polymer face-on orientation. The BHJ blend film of PFBT4T-C5Si-25% showed lower film surface roughness, more balanced hole and electron transport, and relatively smaller phase separation when compared with PFBT4T-C5Si-50%, as evidenced by atomic force microscopy (AFM), transmission electron microscopy (TEM), SCLC, and resonant soft X-ray scattering (RSoXS) measurements.  相关产品： 电子传输材料 cas1480371-38-7 Phen-NaDPO cas2244035-12-7 TRZ-m-Phen cas131159-39-2  C60 cas160848-22-6 PC61BM 空穴传输材料 cas1333317-99-9 PTAA cas472960-35-3 Poly-TPD cas2243991-97-9 S-Poly-TPD cas207739-72-8 Spiro-OMeTAD OPV 给体材料 PTzBI-Cl PFBT4T-C5Si-25% (Si25) NTOD FBT-Th4 OPV 受体材料 cas2304444-49-1 Y6 cas2447642-40-0  Y6-4Cl Y6-2Br Y6-C10C12 Y6-C10C12-4Cl Y6-C10C12-2Br Y6-C10C12-4FNa cas2389125-23-7  Y6-BO Y6-BO-2Br cas2414918-25-3  Y7-BO 以上资料来自小编zhn2021.8.23
