B 2 -B 4 DIMORPHISM IN A NEW SERIES OF BANANA-SHAPED MESOGENS

A new series of five-ring banana-shaped mesogens derived from isophthalaldehyde was synthesized and investigated. Some of the compounds exhibit a B 2 -B 4 dimorphism. The mesophases were characterized alternatively by optical methods, X-ray studies, and dielectric and electro-optical measurements.
