Influence of a nitro side group on liquid crystalline properties of trimellitimides

Abstract

Two series of ester imides from trimellitic anhydride as well as 6-nitrotrimellitic anhydride (4-carboxy-6-nitrophthalic anhydride) have been synthesized. Their thermotropic properties have been compared. Only one nitro compound, N-dodecyl-4-[(4′-decyloxybiphenyl-4-yl)oxycarbonyl]-6- nitrophthalimide has shown liquid crystalline properties. © 2006 Verlag der Zeitschrift für Naturforschung.
