Abstract

Physics, Moscow, RussiaWe consider cholesteric liquid-crystalline DNA dispersions, and show thatpolymeric (Dau-Cu) complexes, the so-called bridges, between pairs of DNA molecules may generate a super liquid-crystalline structure (BR-phase), charachterized by a soliton lattice of the spatial distribution of theorder parameter. The BR-phase could have a layered spatial structure andan abnormal optical activity that could have a bearing upon the intenseCD-band observed in DNA-dispersions.

摘要

俄罗斯莫斯科物理研究所我们研究了胆甾相液晶DNA分散体，并表明DNA分子对之间的聚合物（Dau-Cu）络合物，即所谓的“桥”，可能会产生一种超液晶结构（BR相），其特征是序参量空间分布的孤子晶格。BR相可能具有层状空间结构和异常光学活性，这可能与在DNA分散体中观察到的强CD带有关。
