Synthesis of γ-（diphenylthiocarbazonylmercuriphenoxy） propyltrimethoxysilane and its photochromic behavior 卢雪然 Lu Xueran 1 2 first-author 梅嘉 Mei Jia 1 2 盂令芝 Meng Lingzhi 1 2 Department of Chemistry Wuhan University Department of Chemistry Wuhan University Department of Chemistry, Wuhan University Department of Chemistry, Wuhan University Department of Chemistry Wuhan University Department of Chemistry Wuhan University 苯基烯丙醚与三甲氧基硅烷在四（三苯膦）合铂存在下进行硅氢加成,得到γ-（苯氧）丙基三甲氧基硅烷。后者以醋酸汞汞化,再与二苯基硫代卡巴腙反应,得到γ-（二苯基硫代卡巴腙汞基苯氧）丙基三甲氧基硅烷,其结构通过元素分析、红外、质谱和核磁鉴定。将γ-（二苯基硫代卡巴腙汞基苯氧）丙基三甲氧基硅烷溶于甲苯或甲基硅油中,制成的溶液在日光照射下,其颜色在4～30s内从原来的橙红色变成兰紫色,在散射光下又重新回复到原色,时间为10～109s。变色或回复原色的时间与光强度,溶液浓度有关。在其UV和VS连续扫描谱中,其480hm带强度随扫描进行逐渐加强,而590nm带则逐渐减弱 γ-（Phenoxy）propyltrimethoxysilane was synthesizea by hyarosilylation of phenylallylether with trimethoxysilane in the presence of tetrakis（triphenylphosphine）platinum complex as catalyst. It was mercurated with mercuric acetate, and then treated the mercurated product（Hg-Sil）with diphenylthiocarbazone to form the expected product, r-（diphenylthiocarbazonylmercuriphenoxy）propyltrimethoxysilane（P-Sil）. Its structure was identified by elemental analysis, IR, MS, and 1 H NMR. The title compound was dissolved in toluene or methyl silicone oil to make up solution in various concentration When the solution was irradiated under sunlight, its colour changed from normal orange-red to blueviolet within 4-30 sec., and returned to its original colour under diffuse light within 10109 sec., depending on the illumination and the concentration of solution used. In its continously scanning uv and vs spectra, the absorption peak at 480 nm increased intensity and the 590nm peak decreased its intensity with the progress of scanning. 光致变色化合物 二苯基硫代卡巴腙 硅烷 有机硅化合物 Photochromic Compound dithizone silane organosilicon compound 1988-02-01 2021-04-01 2
