Bischler-Napieralski cyclization has been successfully employed to prepare planar S,N-heteroacenes(SNHs) with the analogue structures to 1,10-phenanthroline. The opto-/electrical properties and the packing modes of ...
A novel kind of aromatic diamine, N-(4-(4-(2,6-diphenyl pyridine-4-yl) phenoxy) phenyl)-3,5-diaminobezamide (DPDAB), was synthesized via aromatic nucleophilic substitution of 3,5-dinitrobenzoylchloride with 4-...
A diamine was synthesized by two successive reactions. Nucleophilic reaction of 4-hydroxybenzoic acid with terephthaloyl chloride yielded terephthaloyl bis(4-oxybenzoic) acid. Then reaction of this compound with 1,8...
Aromatic/aliphatic polyamides were synthesized from a diamine monomer, 2,3-bis-p-aminophenylquinoxaline (IV), based on quinoxaline and various dicarboxylic acids of aliphatic, aromatic and heterocyclic. The diamine ...
A diamine containing ether and ester units, as basic monomer for the preparation of polyamides, was prepared via three consecutive reactions. Nucleophilic substitution reaction of 1,4-dihydroxy benzene with 4-nitroben...
