The results of adiabatic calorimetry, mid-infrared spectroscopy, X-ray diffraction, and polarized microscopy of 4-hexyl-4'-isothiocyanatobiphenyl are presented. Apart from the well-known isotropic liquid and smectic phases, calorimetric measurements indicate the existence of two stable crystalline phases. Quantitative analysis of infrared bands enabled the determination of phase transitions, observation of crystallization kinetics, and elucidation of the glass transition of the crystal-like smectic E phase. The structural information about the glass of the smectic E obtained from the diffraction studies is complemented by textures recorded by polarized microscopy.
本文介绍了 4-己基-4'-异硫氰基联苯的绝热量热法、中红外光谱、X 射线衍射和偏光显微镜的结果。除了众所周知的各向同性液体和近晶相之外，量热测量还表明存在两种稳定的晶相。对红外带的定量分析能够确定相变、观察结晶动力学，并阐明类似晶体的近晶 E 相的玻璃化转变。从衍射研究中获得的近晶 E 玻璃的结构信息，通过偏光显微镜记录的纹理得到补充。
