The absorption spectra of 10-(4,6-dichloropyrimidin-5-yl)-5,15-dimesitylcorrole have been studied in 15 solvents. The formation of deprotonated corrole species was found to account for the dramatic changes in the absorption spectra in several solvents. Careful analysis of the relationship between the formation of deprotonated species and solvent properties results in the conclusion that there is no single solvent parameter correlation, and either multiparameter correlations or specific solute-solvent interactions (preferential solvation of the most acidic NH tautomer or perturbation of intramolecular hydrogen bonding in the macrocycle core) should be considered. The fluorescence properties of the deprotonated pyrimidinylcorrole are also reported for the first time and compared to those of free-base and protonated species.
10-（4,6-二氯嘧啶-5-基）-5,15-二间甲苯基卟啉的吸收光谱在 15 种溶剂中进行了研究。发现去质子化卟啉物种的形成解释了在几种溶剂中吸收光谱的剧烈变化。对形成去质子化物种与溶剂性质之间关系的仔细分析得出的结论是，没有单一的溶剂参数相关性，应该考虑多参数相关性或特定的溶质-溶剂相互作用（最酸性 NH 互变异构体的优先溶剂化或大环核内分子内氢键的扰动）。还首次报道了去质子化嘧啶卟啉的荧光性质，并将其与游离碱和质子化物种进行了比较。
