Developmental Study of New Functionality Materials For Energy Storage and Transport.

As new electron donors for有机金属，vinylogues of TTF and radialenes possessing 1,3-dithiol-2-ylidene moieties have been synthesizedand electric propeties of their CT-complexes be studied. Among their CT-complexes withseveral electon acceptors, the 11 complex of bis(1,3-dithiafulvenyl) with TCNQ revealed high electric aonductivity of <sigma>300 K = 16s /cm. Additionally，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 type of organic metalsbecause of their high electon -donating ability and of their high co- planary . the electlricproperties of (4)radialene-TCNQ (or tcneq_4) CT complex and of the PF6 and c10_4 salts of4 . radialene cation radical were investigated in compressed pellet or crystal state，他们的结果suggested the possiblility of o…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.
