摘要
本文介绍了对位四联苯（4P）及其衍生物-4,4'''-双（三甲基硅基）-对位四联苯（TMS-4P-TMS）晶体从溶液中生长的研究结果。研究发现，与 4Р 相比，TMS-4P-TMS 晶体具有更好的生长特性。利用差示扫描量热法完善了 4P 和 TMS-4P-TMS 在封闭坩埚中的相变参数。利用单晶 X 射线衍射法首次解密了三linic 空间群 P\(\bar {1}\) (Z = 2) 中的 TMS-4P-TMS 晶体结构，并在很宽的温度范围内进行了研究。利用希尔斯菲尔德表面法对所研究化合物的晶体进行了结晶分析，并建立了分子间相互作用的模型。
Crystals of para-Quaterphenyl and Its Trimethylsilyl Derivative. I: Growth from Solutions, Structure, and Crystal Chemical Analysis by the Hirschfeld Surface Method
The results of studying the growth of para-quaterphenyl (4P) and its derivative—4,4'''-bis(trimethylsilyl)-para-quaterphenyl (TMS-4P-TMS)—crystals from solutions are presented. It has been established that TMS-4P-TMS crystals exhibit better growth characteristics as compared to 4Р. Parameters of the phase transitions of 4P and TMS-4P-TMS in closed crucibles were refined using differential scanning calorimetry. The crystal structure of TMS-4P-TMS in the triclinic space group P\(\bar {1}\) (Z = 2) has been decrypted for the first time using single-crystal X-ray diffraction and was studied in a wide temperature range. A crystallographic analysis of the studied compounds in crystals was performed using the Hirshfeld surface method, and modeling of intermolecular interactions was performed.
