title: Synthesis and studies of the properties of a liquid-crystalline quaterrylenebis(dicarboximide) by 1H NMR and UV-vis spectroscopies.
abstract: The synthesis of an ionic quaterrylenebis(dicarboximide) 1a, a long-wavelength absorbing mesogen, is described. When compared with its analogue 2a, an ionic perylenebis(dicarboximide), the aromatic protons of 1a exchange with deuterium of concentrated D(2)SO(4) at a dramatically faster rate. In addition, stronger aggregation in aqueous media was observed for 1a.
