Manipulating the sub-units of conjugated co-polymers was a convenient and promising strategy for developing novel functional materials. Here a soluble alternating copolymer (P-Boc) consisted of 9,9-dialkylfluorene and 1,4-diketo-2,5-di(t-butoxycarbonyl)-3,6-diphenyl-pyrrolo[3,4-c]-pyrrole was designed and synthesized. Heating the spin-coated P-Boc film could afford an insoluble polymer film (P-2H)...
Donor–acceptor (D–A) copolymers P1–P4 containing 1,6-naphthodipyrrolidone as acceptor unit are synthesized and characterized. Copolymers P1 and P2 are prepared upon Suzuki coupling of 3,8-di(4-bromophenyl)-1.6-bis(dodecyl)-2,7-dioxo-1,2,6,7-tetrahydronaphtho[1,2-b:5,6-b′]dipyrrole (M1) or 3,8-di-(4-bromophenyl)-1.6-bis(2-octyldodecyl)-2,7-dioxo-1,2,6,7-tetrahydronaphtho[1,2-b:5,6-b′]dipyrrole (M2)...
We report the synthesis and optoelectronic properties of highly soluble poly(9,10-bis(3′,4′-di(2″-ethylhexyloxy))phenyl)-2,6-anthracenevinylene) (HSM-PAV). The key intermediate for the synthesis of HSM-PAV is 2,6-dimethyl-9,10-dibromoanthracene, and the high solubility of HSM-PAV is from the incorporation of lateral 3,4-di(2-ethylhexyloxy)phenyl moieties into the 9,10-positions of anthracene units...
