Résumé
The design, synthesis and liq.-cryst. properties of a family of hybrid compds. which are built from rod-like (oligophenylenevinylene) and disk-like [poly(benzyl ether)] units are reported. All compds. form columnar phases within broad temp. ranges; the mesophases are stable even below room temp. Weak photovoltaic effect was obsd. for the C60-OPV dyad. For the mol. having a terminal OH group, frustration of the hexagonal packing was obsd. and gave rise to a rare phase sequence. For this material, a columnar phase with trigonal symmetry and doubling of the crystallog. lattice was found below the hexagonal columnar phase. [on SciFinder(R)]
