This grant in the Inorganic, Bioinorganic and Organometallic Program funds the research of Professor Alan L. Balch of the University of California at Davis. The oxidation of fullerenes to mono-oxo species will be studied and the oxidized species will used to form electropolymerized thin films, whose reactive and conductive properties will be studied. A family of flat triangular gold(I) complexes, which exhibit remarkable solvoluminescence properties, and analogs with Ag(I), Hg(II) and Tl(I) will be used to construct supramolecular species. The possibility of electron transfer through columns of these triangular clusters will be tested by examining their photoconductive properties. The possibility of charge-transfer complexes forming between the gold clusters (electron donors) and fullerenes (electron acceptors) will be probed. Co-crystallization of fullerenes with porphyrins has already yielded an interesting class of compounds in which the fullerene nests in the porphyrin. This project is concerned with new inorganic materials that exhibit novel redox activity or luminescence. Fullerenes and triangular gold(I) complexes will be used as precursors for constructing the new materials, such as supramolecular arrays and molecular co-crystals. Fullerene films will be explored as new highly conductive materials. A new form of luminescence called solvoluminescence, which is light emitted upon the dissolution of a previously irradiated substance, will be studied. The hypothesis that this results from a long range separation of an electron from its original site in a column of triangular gold units will be tested. Understanding such charge separations is fundamental to our understanding of natural energy storage and transduction devices and developing new materials along these lines. Information gained from either fullerene or triangular gold precursor classes will have an impact on how the other class is developed and their combination may lead to entirely new materials. Porphyrin complexes that can wrap partially around fullerenes will be used to develop new ways of chromatographically separating fullerene molecules according to their various shapes, which may make unusual fullerenes more available for development.

无机、生物无机和有机金属项目的这笔赠款资助了加州大学戴维斯分校的艾伦·L·鲍尔奇教授的研究。我们将研究富勒烯氧化成单氧物种，并利用氧化物种形成电聚合薄膜，研究其反应和导电性能。一族平面三角形金(I)络合物将被用来构建超分子物种，它们具有显著的溶液发光性质，并与Ag(I)、Hg(II)和Tl(I)类似。将通过检查这些三角形团簇的光导性能来测试电子转移通过这些三角形团簇的柱子的可能性。我们将探讨在金原子簇(电子供体)和富勒烯(电子受体)之间形成电荷转移络合物的可能性。富勒烯和卟啉的共结晶已经产生了一类有趣的化合物，其中富勒烯嵌在卟啉中。这个项目是关于表现出新的氧化还原活性或发光的新型无机材料。富勒烯和三角金(I)络合物将被用作构建超分子阵列和分子共晶等新材料的前驱体。富勒烯薄膜是一种新型的高导电性材料。我们将研究一种新的发光形式，称为溶胶体发光，它是在先前被照射的物质溶解时发出的光。这一假设是由于电子在一列三角形的金单元中与其原始位置远距离分离而产生的，这一假设将得到检验。了解这种电荷分离对于我们理解自然能量存储和转换设备以及沿着这些路线开发新材料是基本的。从富勒烯或三角金前驱体类获得的信息将对另一类的发展产生影响，它们的结合可能导致全新的材料。可以部分包裹在富勒烯周围的卟啉络合物将被用来开发根据富勒烯的不同形状对富勒烯分子进行色谱分离的新方法，这可能会使不寻常的富勒烯更容易开发。
