  Crystalline - Smectic C - Cubic - Isotropic - Nematic - Isotropic Polymorphism: Synthesis and Unexpected Behaviour of a New Series of Double-Swallow-Tailed Mesogens

  摘要：

  A new homologous series of six-ring double-swallow-tailed mesogens was prepared and investigated. Liquid-crystalline properties strongly depend on the length of the terminal alkyl chains. Six different phase sequences could be detected, two of them were unknown up to now. The derivatives DS-5...7 show smectic C, cubic and nematic phases, the longer-chain homologues DS-10...14, 16 have columnar phases. The substance DS-8 exhibits the most interesting phase sequence cr - S-C - cub - I-re - N - I. DS-8 represents the second pure compound with a stable reentrant isotropic phase. Optical, X-ray, and further investigations provide arguments to propose the structures of the different phases.

  The present application describes improved compositions for wellbore fluids for use in downhole (e.g. oilwell) applications. The compositions comprise a blocked isocyanate (BI) component having a tolerance improving group (such as a hydrophilic group, e.g. an amine) bonded to it, and an active hydrogen component. When the BI group is unblocked, it reacts with the active hydrogen component to form a gel which, by virtue of the tolerance improving group, is more tolerant to contaminants (such as aqueous inorganic salts or brines) than the corresponding gel forms from unmodified BI. The application also relates to methods of treating an earthen formation using such a composition.
