Synthesis of phenanthro[b] phenazine, a novel heterocyclic ring structure for discotic liquid crystals
Phenanthro[b]phenazine. a new heterocyclic ring structure of both biological and physical interests, has been prepared by coupling 1, 2-phenylenediamine with triphenylene-2, 3-quinone derivative. The first derivative of this novel core, 2,3,6,7-tetrapentyloxyphenanthro[b]phenazine shows a monotropic columnar phase.
