Asymmetric dibenzophospholes: new phosphorus-based chiral liquid crystals
摘要:
(S-p,S-c)-5-Ethyl-3-(2-methylbutoxy)-7-(4-undec-10-enoxyphenoxycarbonyl)-5H-dibenzophosphole 5-oxide, the first example in the literature of a new asymmetrically substituted dibenzophosphole-based group of systems with liquid-crystal properties is described.
