摘要
Mesomorphic properties of S-alkylthiopentonolactones (n-ribono, D-arabinono and D-xylono) and corresponding alditol derivatives with the general formula Su SR (R = CnH2n+1; n = 5-12) are studied. It was shown that the thermotropic and lyotropic phase transition temperatures are influenced by the following structural parameters: alkyl chain length, cyclic or acyclic Su structure and alditol conformation. Besides, it seems that n parity affects thermotropic phase transition temperatures. (C) 2014 Elsevier Ltd. All rights reserved.
