1B21 Molecular Design Stabilizing the Anticlinic Structure

Abstract

Control of the clinicity in the smectic phases is a challenging research topic in the filed of liquid crystal chemistry. Two new molecular designs for stabilizing the anticlinic structure were introduced and the origin of the anticlinic ordering discussed : (a) introduction of a phenyl ring at each terminal end of the molecular structure showed a significant effect on the determination of the clinicity, and (b) a trimeric molecular architecture promoted the micro-segregation between weakly distinct moieties, i. e., the aromatic rigid cores and the aliphatic flexible spacers, producing a well-defined smectic layered structure and thus stabilizing the anticlinic order.
