Abstract
The synthesis and the liquid crystalline properties of a new class of conjugated derivatives that assembled four oligophenylenevinylene (OPV) moieties arising from a calix[4]arene core are described. Photophysical investigations also revealed strong electronic coupling between the four OPV fragments of the calix[4]OPV derivative.
