13 Azomethines have been prepared from 2-amino-9,10-dihydrophenanthrene by reaction with aromatic aldehydes.Those with p-alkoxy, p-cyano or p-phenyl substituents in the aldehydic ring have a nematic mesophase.U.v. spectra, 1H and 13C n.m.r. spectra, and mass spectra of the series are discussed.Mass spectra show that ortho-substituents in the aldehydic ring substantially modify the fragmentation pattern.
