Bistable linear electro-optical switching in the B7′ phase of novel bent-core molecules†
Abstract
Three novel symmetrical bent-core compounds were synthesized where the terminal alkoxy linkages of the original bent-core mesogen forming a B2 phase was converted to n-alkyl carboxylates. It is found that instead of the B2 phase, all three compounds exhibit a transition between B7′ and B2 mesophases. The physical and electro-optical properties have been investigated by
