Further Understanding on the Measurement Methods for Solid-State Circular Dichroism Spectroscopy——Discussion on Concentration Effects

对近期发展的固体圆二色(Cd)光谱测试方法进行了概述、评价和比较,着重探讨了“浓度效应“的存在使固体Cd光谱失真的原因.通过对本课题组和其他作者已报道的四种化合物的固体Cd谱再测试的反思,强调了依手性化合物的手性光谱学性质不同,根据浓度梯度实验选择其合适测试浓度的必要性.对固有手性的阻转异构化合物(S)-1,1-联二萘酚(S-bInOl)进行了成膜法固体Cd谱浓度梯度测试,发现所得固体薄膜Cd谱中也存在着“浓度效应“.In this paper, the recent developments in measurement methods of solid-state circular dichroism(CD) spectroscopy were summarized and discussed, especially the effects of concentration on solid-state CD spectral distortions.By reinspection and introspection of the solid-state CD spectra of four reported compounds, concentration gradient measurements were proved to be necessary for appropriate concentrations, which are greatly related to the chiroptical properties.The thin film solid- state CD measurements of the inherently chiral atropisomer(S)-1,1'-bi-2-naphthol(S-BINOL) were carried out with concentration gradient measurements.Using this film- state technique for the first time, the results show some subtle correlations between the CD curves and the special concentrations.国家自然科学基金(21273175;21271150;21001026); 中国科学院福建物质结构研究所结构化学国家重点实验室基金(20110006;20130008)资助项目~
