项目摘要

As new electron donors for organic metals, vinylogues of TTF and radialenes possessing 1,3-dithiol-2-ylidene moieties have been synthesized, and electric propeties of their CT-complexes have been studied. Among their CT-complexes with several electon acceptors, the 1 : 1 complex of bis( 1,3-dithiafulvenyl ) with TCNQ revealed high electric aonductivity of <sigma> 300゜K = 16 S/cm. Additionally, the electric conductivity of the complex showed a temperature dependence ressmbling that of metal, indicating that the complex is undoubtedly " organic metal ". The new radialenes, in particular (3)radialene, are expected as desirable electron donors for new types of organic metals, because of their high electron-donating ability and of their high co-planarity.The electlric properties of (4)radialene-TCNQ ( or TCNQE_4 ) CT complex and of the PF6 and C10_4 salts of (4)radialene cation radical were investigated in compressed pellet or crystal state, and their results suggested the possiblility of o … More rganic metals. A possibility preparing the mixed valency state was also suggested.A number of the donor-acceptor norbornadienes has been prepared, and their efficiencies of storing light energy under solar insolation have been assessed experimentally.2,3-Dicyano-4,5,6-trimethylnorbornadiene showed the fighest efficiency. The chemical conversion of the norbornadiene to the corresponding quadricyclane under insolation was 5 mol/m^2 day for a typical run which was close to the theoretical one, 6 mol/m^2 day. The development study of the heterogeneous catalyst for the energy-releasing process has been performed begining with a series of fundamental studies including screening of metal elements, reaction mechanisms of metal catalysed cycloreversion, methods for immobilization of catalyst and so forth. Consequently, an excellent heterogeneous catalyst for the cycloreversion of trimethyldicyanoquadricyclane has been found, which revealed many prominent properties, high activity, small deactivation rate and moreover ability of restoration of activity by heating the used catalyst under vacuo.

作为有机金属的新型电子给体，合成了含1，3-二硫-2-亚甲基的四氢呋喃和径烯类化合物，并研究了它们的电学性质。其中，双(1，3-二硫代富烯基)与TCNQ的1：1络合物表现出较高的电导率，其电导系数K=16 S/cm。此外，该络合物的电导率表现出与金属的电导率相同的温度依赖性，表明该络合物无疑是有机金属。本文研究了(4)径烯-TCNQ(或TCNQE_4)CT络合物和(4)辐烯阳离子自由基的Pf6和C10_4盐在压片和晶态下的电学性质，结果表明o…是可能的更多的有机金属。还提出了一种制备混合价态的可能性。已经制备了一些给体-受体降冰片二烯，并对它们在太阳照射下的储能效率进行了评估。experimentally.2，3-Dicyano-4，5，6-trimethylnorbornadiene显示出最大的储能效率。在光照条件下，降冰片二烯向相应四环烷的化学转化率为5 m o l/m~2·d，接近理论值6 m o l/m~2·d。从金属元素的筛选、金属催化的环回反应机理、催化剂的固定化方法等一系列基础性研究入手，开展了用于能量释放过程的多相催化剂的开发研究。因此，找到了一种性能优异的三甲基二氰基四环烷环还原催化剂，该催化剂具有活性高、失活速率小以及在真空下加热即可恢复活性的特点。较少
