| 英文摘要 | Two new low-bandgap, conjugated donor (d) acceptor (a) copolymers of porphyrin with 2,3-bis(4-trifluoromethylphenyl)pyrido[3,4-b]pyrazine (p1) and perylene diimide (p2) were synthesized by sonogashira coupling polymerization and compared with porphyrin-dithienothiophene d-d copolymer (p3). all these polymers possess good thermal stability with decomposition temperatures over 300 degrees c. polymers p1 and p2 in films exhibit strong absorption in near-ir (820-950 nm) with optical bandgaps as low as 1.15 ev; their q-bands red shift 60 190 nm compared to that of p3, while the soret bands are similar. the homo (-5.3 to -5.4 ev) and lumo (-3.6 to -4.0 ev) of the d-a polymers are lower than that of the d d polymer. two-photon absorption (2pa) properties of the polymers were investigated by the femtosecond z-scan method. the d a polymer p2 exhibits 2pa cross sections over 7000 gm/repeat unit at telecommunication wavelengths (1320 and 1520 nm), larger than that of pi and p3, due to the very strong, rigid, and coplanar perylene diimide acceptor and strong d-a intramolecular charge transfer. |
