This subproject is one of many research subprojects utilizing the resources provided by a Center grant funded by NIH/NCRR. The subproject and investigator (PI) may have received primary funding from another NIH source, and thus could be represented in other CRISP entries. The institution listed is for the Center, which is not necessarily the institution for the investigator. Organic molecules in unusual oxidation states. Our investigations of dopants for organic molecular semiconductors have led to the synthesis and isolation of number of unusual molecules. For example, we have isolated the first antiaromatic porphyrin complex, Si(TPP)(THF)2, shown to the right. New Semiconducting Materials. Inorganic. We have synthesized several members of a new class of materials, metal-sulfur-organic networks. Their crystal structures have been determined either by single-crystal X-ray diffraction or synchrotron X-ray powder diffraction. Some of these materials are semiconducting: an example is [Pb3(C6S6)]n, shown to the right. Organic. While a large number of 1-dimesional conjugated polymers are known, 2-dimesional conjugated materials are essentially unknown. A graphene sheet is one example. We have synthesized new graphite-like 2-dimensional conjugated materials, and the physical properties of those materials are being studied.

这个子项目是许多研究子项目中的一个 由NIH/NCRR资助的中心赠款提供的资源。子项目和 研究者（PI）可能从另一个NIH来源获得了主要资金， 因此可以在其他CRISP条目中表示。所列机构为 研究中心，而研究中心不一定是研究者所在的机构。 不寻常氧化态的有机分子。我们对有机分子半导体掺杂剂的研究已经导致了许多不寻常分子的合成和分离。例如，我们已经分离出第一个反芳香卟啉配合物Si（TPP）（THF）2，如右图所示。 新型半导体材料无机物。我们已经合成了一类新材料（金属硫有机网络）的几个成员。用单晶X射线衍射和同步辐射X射线粉末衍射测定了它们的晶体结构。其中一些材料是半导体的：一个例子是[Pb 3（C6 S6）]n，如右图所示。 有机的虽然已知大量的一维共轭聚合物，但二维共轭材料基本上是未知的。石墨烯片是一个示例。我们已经合成了新型的类石墨二维共轭材料，并且正在研究这些材料的物理性质。
