The primary goal of this research program is the advancement of the relatively underdeveloped synthetic and structural chemistry of a class of heavy metals, known as the heavy p-block metals. This is being achieved through the preparation and characterization of series of compounds which systematically highlight heavy metal chemical bonding interactions. Over the past number of years, interest in organometallic compounds incorporating heavy p-block metals has grown due to their utility as precursors for advanced production of inorganic materials with specific electronic properties, such as low band-gap semiconductor thin films (InP) and nanoparticles (PbS), and high temperature superconductors thin films (TlBaCaCuO). We are developing methods to manipulate the structural chemistry of heavy p-block metal compounds, which is essential for the preparation of precursors with specific bulk properties (e.g. increased solubility, high volatility, efficient mass transport) required for advanced inorganic materials processing. This work is also significant to several other areas of fundamental and applied chemistry, namely: 1) synthetic inorganic/organometallic chemistry, in the development of facile routes to novel heavy p-block metal compounds; 2) supramolecular chemistry, through incorporation of heavy p-block metals into interesting self-assembled frameworks; and 3) catalysis, through the preparation of cationic bismuth compounds which are potentially reactive toward organic compounds. The long-term goals of this research program involve investigating the application of target compounds to these areas.

这项研究计划的主要目标是推进相对不发达的一类重金属的合成和结构化学，被称为重p块金属。这是通过系统地突出重金属化学键相互作用的一系列化合物的制备和表征来实现的。在过去的几年里，人们对含有重p块金属的有机金属化合物的兴趣越来越大，因为它们可以作为具有特定电子性能的先进无机材料的前体，如低带隙半导体薄膜（InP）和纳米颗粒（PbS），以及高温超导体薄膜（TlBaCaCuO）。我们正在开发方法来操纵重p嵌段金属化合物的结构化学，这对于制备先进无机材料加工所需的具有特定体积性质（例如增加溶解度，高挥发性，高效质量传输）的前驱体至关重要。这项工作对基础化学和应用化学的其他几个领域也很重要，即：1)合成无机/有机金属化学，在开发新的重p嵌段金属化合物的便捷途径方面；2)超分子化学，通过将重p块金属结合到有趣的自组装框架中；3)催化，通过制备对有机化合物具有潜在反应性的阳离子铋化合物。这项研究计划的长期目标包括研究目标化合物在这些领域的应用。
