New structure, bonding and reactivity paradigms for the group 15 and 16 elements

目前主要基团化学领域的研究为分子结合的方式(化学结构和成键)提供了实质性的见解。这对评估此类化合物的实用材料有很大帮助。这种类型的调查主要是一项学术研究，但许多结果已经转化为可观的经济效益。主族元素在电子材料、医药和新型塑料中的作用日益突出。构建新的主族元素化合物的好处有两个：(A)增加了对结构、成键和反应性的基本原理的了解；(B)这种知识可用于评估增值产品的潜在应用。在这种情况下，分离含有带电主族中心的新化合物或非常规成键排列中的主族中心是可取的，因为它们具有很高的反应活性。在过去的两年半里，我们的团队继续开展了一项研究计划，重点是研究各种主要族元素的基本化学，以及开发我们的发现的潜在新应用。我们当前计划中的两个主题已被确定为进一步发现、开发和扩展的极佳候选主题，这也是当前发现拨款提案的基本目标，其中包括以下新目标：(I)利用上文(A)部分的发现，开发新颖的硫族/pNictogen配位结构和应用化学；(Ii)利用创新配体确定第15和第16族元素的新颖原子排列、反应性和材料化学；以及(Iii)对我们的高度氟化疏水/憎油、亲离子材料进行新的修饰，从而将这些疏水性能赋予各种分子和表面。

Current research in the field of Main Group chemistry provides substantial insight into the way molecules are held together (chemical structure and bonding). This greatly assists in the assessment of such compounds practical materials. Investigations of this type are primarily an academic study, however many of the results have translated into substantial economic benefit. Main group elements are playing increasingly prominent roles in electronic materials, pharmaceuticals and new plastics. The benefits for the construction of new main group element compounds are two fold: (a) an increased understanding of the fundamentals of structure, bonding and reactivity; and (b) this knowledge can be used to assess potential applications for value-added products. In this context, the isolation of new compounds that contain charged main group centres, or main group centres in unconventional bonding arrangements are desirable because of their high reactivity. Our group has, over the last 2.5 years, continued a research program that centres on investigating the fundamental chemistry of a variety of main group elements, as well as developing the potential new applications of our findings. Two of themes from our current program have been identified as excellent candidates for further discovery, development and expansion, which are the foundational goals for this current Discovery Grant Proposal, which includes the following new objectives: (i) Utilizing the discoveries from part (a) above, to develop novel chalcogen/pnictogen dicationic constructs and applied chemistry; (ii) To utilize innovative ligands in identifying novel atom arrangements, reactivity and materials chemistry for the elements of Group 15 and 16; and, (iii) New modifications to our highly fluorinated hydrophobic/oleophobic, ionophilic materials that will impart these phobic properties onto a wide variety of molecules and surfaces.
