项目摘要

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.

在该项目中，利用八面沸石和磷酸铝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，得到以下结果： 1．发现预装在 Y 型沸石晶格空间中的铜、铬和铁离子非常适合作为聚合引发剂。进一步发现，虽然随着Cu-NaY中Cu(II)含量的增加，生成的聚吡咯簇的数量增加，但它们的热稳定性降低，并且聚吡咯簇的电子态转变为双极化子。立体化学模拟表明Y沸石中的聚吡咯簇链可能沿着相互垂直的[110]方向排列。2．结果发现，六方八面沸石晶格空间中合成的聚噻吩簇的量取决于作为聚合引发剂的Cu(II)含量，且呈双极化状态。 3．发现以铬离子为氧化剂，在磷酸铝分子筛AlPO_4-5的一维孔道中成功合成了电子态主要为极化子的导电聚吡咯团簇。 4．发现磷酸铝分子筛、AlPO_4-5 和 VPI-5 中的非线性光学性质是通过将对硝基苯酚簇封装在其一维通道中而产生的。
