In situ UV Vis spectra for protonic acid doping reaction of polyaniline in organic solvent were recorded. The doping reaction mechanism was obtained from the chemical factor analysis for the first time. 对聚苯胺在有机溶剂中掺杂质子酸的反应进行了in-situUV-Vis光谱跟踪,用因子分析法对掺杂反应机理进行了研究。
Trans 4 styrylpyridine and its derivatives were prepared with high yields in polar non protonic solvent with potassium hydroxide as catalyst. 以KOH为催化剂,在极性非质子性溶剂中,以较高收率合成了反-4-苯乙烯基吡啶及其衍生物。
For example, fluorescent molecules will be quenched in protonic solvents. The main reason is the modification effect of hydrogen bond between solute and solvent molecules. 比如,很多具有荧光性质的分子在质子性溶剂中会发生荧光淬灭,主要原因就是溶质与溶剂分子之间氢键相互作用对体系电子激发态性质的调节作用。
