New random copolymers with pendant carbazole donor and 1,3,4-oxadiazole acceptor for high performance memory device applications

New non-conjugated random copolymers containing pendent electron-donating 9-(4-vinylphenyl)carbazole (VPK) and electron-accepting 2-phenyl-5-(4- vinylphenyl)-1,3,4-oxadiazole (OXD) or 2-(4-vinylbiphenyl)-5-(4-phenyl)-1,3,4- oxadiazole (BOXD) were successf

2-(BIPHENYL-4-YL)-5-PHENYL-1,3,4-OXADIAZOLE (PBD): ELECTROPHILIC 4'-SUBSTITUTION AND FOLLOWING TRANSFORMATIONS

PBD was converted into 4'-substituted derivatives I-XII using usual electrophilic reagents.The decompositions of PBD, 4'-acetyl derivative I and 4'-nitro derivative VI with hydroiodic acid gave 4'-substituted 4-biphenylcarboxylic acids XIIIa-XIIIc and benzoic acid, respectively.The regioselectivity of the reactions was also proved by means of high resolution NMR spectroscopy.
