Using 2-amino-3-substituted benzoic acid as starting material, 4, 5-disubstituted phenanthrene derivatives were synthesized via sequential reactions of diazotization-coupling reaction, esterification, reduction, oxidation and cyclization, and using reduced biphenyl intermediates as starting materials. 4, 5-Disubstituted 9, 10-dihydrophenanthrene derivatives were syn-thesized via sequential reactions of bromination, grinard reaction, using 4, 5-disubstituted phenanthrene and 4, 5-disubstituted 9, 10-dihydrophenanthrene derivatives as starting materials. Liquid crystal monomer compounds were synthesized via sequential reactions of halogenations and coupling reaction, and the chemical structures of products were identified by 1H NMR, 13C NMR spectra.
