(d-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
研究了S-烷硫基戊内酯(d-核糖基,d-阿拉伯糖基和d-木糖基)和相应的通式为Su-SR(R = CnH2n + 1; n = 5-12)的糖醇衍生物的介晶性质。结果表明,热致相变温度受以下结构参数的影响:烷基链长,环状或无环Su结构和糖醇构象。此外,似乎n平价会影响热致相变温度。
