Here, we describe the synthesis and characterization of a silyl protected tetraphenylimidazole monomer and its homo and co-polymer. The requisite monomer was accessed by Suzuki–Miyaura cross-coupling of 2-(1-(4-bromophenyl)-4,5-diphenyl-1H-imidazol-2-yl)phenol and 4-vinylphenylboronic acid followed by protection of the phenolic group by tert-butyl(chloro)diphenylsilane. The desired polymers were readily synthesized by using free radical polymerization. Both the polymers and monomer were characterized using different analytical techniques including multinuclear NMR, GPC (for polymers), and single crystal X-ray crystallography (for the monomer). By utilizing the greater fluorophilicity of the silyl atom, the polymers were studied as probes for the detection of fluoride ions. The selectivity and sensitivity of the synthesized polymers were investigated in detail.

聚四苯基咪唑的合成与表征及其在氟离子检测中的应用

在这里，我们描述了甲硅烷基保护的四苯基咪唑单体及其均聚物和共聚物的合成和表征。通过 2-(1-(4-溴苯基)-4,5-二苯基-1 H-咪唑-2-基)苯酚和 4-乙烯基苯基硼酸的 Suzuki-Miyaura 交叉偶联获得必要的单体，然后保护酚类按叔-丁基(氯)二苯基硅烷。通过使用自由基聚合很容易合成所需的聚合物。使用不同的分析技术对聚合物和单体进行表征，包括多核 NMR、GPC（用于聚合物）和单晶 X 射线晶体学（用于单体）。通过利用甲硅烷基原子更大的亲氟性，研究了聚合物作为检测氟离子的探针。详细研究了合成聚合物的选择性和灵敏度。
