有机金属前驱体的设计、合成和选择性热解转化为高纯度或特定形貌的材料(用于电子或光学应用)、高强度和/或高温稳定性(用于结构或耐火材料应用)是化学和材料科学(材料化学)重叠领域极具发展潜力的领域。这一领域的研究可能会在学术和社会两级产生相当大的影响,因为它将需要在目前尚未得到很好理解的领域发展科学专门知识。例如:(1)200℃以上金属有机分子中分子重排的热力学;(2)非晶态陶瓷材料的电子性质;(3)陶瓷分子复合材料的物理化学性质;(4)通过溶胶-凝胶工艺制备的多元玻璃的光学性质。要有机会建立在“材料化学”中追求有用研究目标所需的科学原理,就需要化学家、陶艺学家、冶金学家和物理学家之间的交流。到目前为止,几乎没有机会创造一种可能发生这种交流的环境。这次北约高级研究研讨会的目的是促进与“材料化学”相一致的不同领域的专家之间的讨论。这些讨论旨在确定以下研究工作的范围和潜在回报:普通材料和外来材料的定制设计的前体,有选择地将这些前体高产量转化为所需材料的方法,以及表征最终产品的方法。
The design, -synthesis, and selective pyrolytic conversion of organo metallic precursdrs to materials of high purity or specific morphology (for electronic or optical applications), high strength and/or high-temperature stability (for structural or refractory applications) represents a poten tial area of extreme growth at the overlap of chemistry and materials science (materials chemistry). Research in this area is likely to have considerable impact at both the academic and societal levels because it will require development of scientific expertise in areas currently not well understood. Examples include: (1) The thermodynamics of molecular rearrangements in organometallic molecules at temperatures above 200 C; (2) The electronic properties of amorphous ceramic materials; (3) The phys icochemical properties of ceramic molecular composites; and (4) The optical properties of multicomponent glasses made by sol-gel processing. The opportunity to establish the scientific principles needed to pursue useful research goals in "materials chemistry" requires communica tion between chemists, ceramists, metallurgists, and physicists. To date, there have been few opportunities to create an environment where such communication might occur. The objective of this NATO Advanced Research Workshop was to promote discussions between experts in the varibus disci plines aligned with "materials chemistry. " These discussions were intended to identify the scope and potential rewards of research efforts in the development of: Custom-designed precursors to common and exotic materials, methods of selectively transforming these precursors in high yield to the desired material, and methods of characterizing the final products."
