Two novel compounds, 1,4,5,8-tetra-(4-n-butoxy-carbonyl)-naphthalene and 1,4,5,8-tetra-(8-n-octoxy-carbonyl)-naphthalene, were prepared from 1,4,5,8-naphthalene tetracarboxylic acid(NTA) with tetraoctane-ammonium bromide as a phase transfer catalyst. Their UV-Vis and fluorescent spectra suggested that the two compounds formed excimer complex in CH2Cl2, respectively. Their liquid crystalline behavior was investigated by DSC and polarized optical microscopy and their thermotropic liquid crystalline behavior was observed.
