Study of structural control and multi-functionarization of self-organized porphyrin assemblies

基于非共价弱相互作用对大规模自组织分子结构的基础研究，发展了利用环糊精对水溶性卟啉的包合能力来组装多个卟啉的新方法。本文报道了一种每面含4个环糊精的主体卟啉的合成，即共8个环糊精，它与水溶性的锌卟啉形成了卟啉组合物。ZTPPS向中心宿主游离碱基孔的能量传递效率受立体排列的影响。这些观察表明，组装中的光功能可以由分子结构自由控制。

Upon basic research of large scale self-organized molecular structures by non-covalent weak interactions, new methodology have been developed for multi-porphyrin assemblies using inclusion abilities of cyclodextrin for water soluble porphyrins. Here, Synthesis of a host porphirin with 4 cyclodexistrins of each surfaces, that is, total 8 cyclodextrins, which formed porphyrin assemblies with water soluble zinc porphirin (ZnTPPS) were reported. Sterical arrangements were affected for energy transfer efficiency from ZTPPS to central host freebase porphirn. These observations indicated that photo functions in assembly could be freely controlled by the molecular structure.
