项目摘要

Introduction In the last fiscal year of this project, Assits. Prof. T.Shichi has been delivered at the laboratory of Professor Lamamurthy at Tulane University for three months in order to carry a out cooperative work on chiral-induced photoisomerization of cyclopropane derivatives incorporated in zeolite cavities. The zeolite photochemistry is not only one of the field in which Prof. Lamamurthy is a leader in the world, but also a very comparable to the clay photochemistry on the point of the common nature of ionically charged porous materials. It is expected that his training in the zeolite photchemistry will provide a fruitful knowledge for the clay photochemistry.On the other hands in Japan, Profs. Inoue and Takagi have undertaken a cooperative work on the hybridization of fluorinated surfactants and montmorrilonite clay minerals. They have resolved the 3 dimensional structure of the hybrid by means of polarized uv and sisible spectrophotometories. These results were published at the 24th Symposium of the Fluorine Chemistry in Kyoto and also a part of them has published in the Journal listed later.Experimental Poliflurinated surfactants(C3F-S, C8F-S)(Rf=CONHC2H4NMe2Cl6H33), Rose Bengal(RB)and porphyrin drivatives were intercalated in Sumecton SA(Kunimine Kogyo)to give hydrophobic powders. The characterization of the hybrids were carried out by conventional NMR spectrometry.The results and Discussion The polarized infra red spectrophotometry revealed the C3F-S and C8F-S molecules are stacked in a from of bilayer unit which are tilted approximately 30° in these clay hybrids layers. When RB or MTSPP are co-incorpotaed in these clay layers, it is evident to localized and tend to be aggregated in rather less polar circumstance.

在本项目的最后一个财政年度，Assits。T.Shichi教授在杜兰大学Lamamurthy教授的实验室工作了三个月，以开展沸石空腔中环丙烷衍生物手性诱导光异构化的合作工作。沸石光化学不仅是Lamamurthy教授在世界上处于领先地位的领域之一，而且在离子带电多孔材料的共同性质上也是与粘土光化学非常相似的领域。他在沸石光化学方面的训练将为粘土光化学提供丰富的知识。Inoue和Takagi进行了一项关于氟化表面活性剂和蒙脱土粘土矿物的混合的合作工作。他们用偏振紫外光谱和扫描电镜解析了杂化物的三维结构。这些结果发表在京都的第24届氟化学研讨会上，其中一部分也发表在随后列出的杂志上。实验性的多氟表面活性剂（C3 F-S，C8 F-S）（Rf= CONHC 2 H 4 NMe 2Cl 6 H 33）、玫瑰红（RB）和卟啉驱动剂插入Sumecton SA（Kunimine Kogyo）中，得到疏水粉末。结果与讨论偏振红外光谱分析表明，C_3F-S和C_8 F-S分子以倾斜约30°的双层单元形式堆积在粘土杂化层中。当RB或MTSPP在这些粘土层中共混时，很明显，在极性较低的环境中，RB或MTSPP会局部化并倾向于聚集。
