Simple chiral recognition method of 2-alkylalcohols on a silica gel plate was proposed by using the induced circular dichroism (ICD) of J-aggregates of diprotonated tetraphenylporphyrin and magnetic circular dichroism (MCD) spectrometry. To the silica gel on a glass slide including a chiral 2-alkylalcohol and 4 M sulfuric acid, the porphyrin in toluene was added and mixed. Then, the glass slide was used for in situ MCD measurement. The observed ICD spectra could recognize well the chirality of the alcohols and the ICD intensity normalized by the MCD intensity of the J-aggregate correlated linearly to the amount of the chiral alcohols in the silica gel.

硅胶板上卟啉J-聚集体的磁性圆二色性手性识别2-烷基醇
利用二质子化四苯基卟啉J-聚集体的诱导圆二色性（ICD）和磁圆二色性（MCD）光谱法，提出了硅胶板上2-烷基醇的简单手性识别方法。向包含手性2-烷基醇和4M硫酸的载玻片上的硅胶中，添加卟啉在甲苯中的混合。然后，将载玻片用于原位MCD测量。观察到的ICD光谱可以很好地识别醇的手性，并且通过J聚集体的MCD强度归一化的ICD强度与硅胶中手性醇的量线性相关。
