Study on Synthesis and Structural Chemistry of Microcluster in Lattice Space of Zeolites and Related Compounds

本项目利用faujasites和铝磷酸分子筛的晶格空间合成了导电和光学微团簇，并通过各种方法进行了研究。通过调查，发现了以下结果：在Y型沸石的晶格空间中预装铜、铬和铁离子是聚合的引发剂。进一步发现，虽然随着Cu （II）含量的增加，聚吡咯团簇的数量增加，但其热稳定性降低，聚吡咯团簇的电子态转变为双极化子。立体化学模拟表明，Y型沸石中的聚吡咯簇链可能沿相互垂直的方向分布[110]。结果表明，在六方faujasites的晶格空间中合成的多噻吩簇的数量取决于Cu （II）的含量，它们表现为双极化子态。以铬离子为氧化剂，在磷酸铝分子筛AlPO_4-5的一维通道中成功地合成了电子态以极化子为主的导电聚吡咯团簇。在磷酸铝分子筛AlPO_4-5和VPI-5中，对硝基酚簇包封在其一维通道中，产生了非线性光学性质。

In this project, conducting and optical microclusters have been synthesized, using lattice spaces of faujasites and aluminophosphate molecular sieves, and investigated by means of various methods. The following results were found through the investigation.1. Copper, chromium and iron ions preloaded in the lattice space of zeolite Y were found to be well suited for initiater of polymerization. It was, further, found that although an amount of produced polypyrrole clusters increased with increasing Cu (II) contents in Cu-NaY,their thermal stabilities decreased and the electron state of ploypyrrole clusters were transformed into bipolaron. Stereochemical simulation suggested the possibility that polypyrrole cluster chains in zeolite Y were located along the mutually perpendicular [110] directions.2. It was found that an amount of polythiophen cluster synthesized in the lattice spaces of hexagonal faujasites depended on Cu (II) contents as initiater of polymerization, and they exhibited bipolaron state.3. It was found that conducting polypyrrole clusters, whose eelctron state was mainly polaron, wre successfully synthesized in one-dimensional channels of aluminophosphate molecular sieve, AlPO_4-5, with chromium ions which acted as oxidizing agents.4. The nonlinear optical properties were found to be generated in aluminophosphate molecular sieves, AlPO_4-5 and VPI-5, by encapsulating p-nitrophenol clusters in their one-dimensional channels.
