	%X A homologous series of aromatic esters, 4-nalkanoyloxybenzylidene-
4--bromoanilines, nABBA,
consisting of two 1,4-disubstituted phenyl cores and a Schiff
base central linkage was synthesized. All the members can be
differed by the number of carbon atoms at terminal
alkanoyloxy chain (CnH2n-1COO-, n = 2, 6, 18). The molecular
structure of nABBA was confirmed with infrared
spectroscopy, nuclear magnetic resonance (NMR)
spectroscopy and electron-ionization mass (EI-MS)
spectrometry. Mesomorphic properties were studied using
differential scanning calorimetry and polarizing optical
microscopy.
