Strained and unstrained metallacyclophanes and reactive intermediates

较重的13族元素Al、Ga和In在我们的现代生活中扮演着重要的角色。除了铝作为块状金属和合金组分的明显存在外，有机金属丙烷还间接以聚合物(Ziegler/Natta聚合)和电子器件(化学气相沉积，CVD)的形式存在。有机金属铝化合物基础知识的匮乏与元素的重要性形成了鲜明对比。镓是现代电子设备中的关键元件；例如，砷化镓是当今已知的第二重要半导体。铟作为基本的掺杂剂用于合金和半导体材料中。我们的主要研究活动集中在较重的13族元素铝、镓和铟的化学上。

The heavier group 13 elements Al, Ga, and In play an important role in our modern life. Apart from aluminum's obvious presence as a bulk metal and as a component in alloys, organometallic alanes are indirectly present in the form of polymers (Ziegler/Natta type polymerization) and electronic devices (Chemical Vapor Deposition, CVD). The dearth of basic knowledge about organometallic aluminum compounds contrasts with the importance of the element. Gallium is the key component in modern electronic devices; e.g., GaAs is the second most important semiconductor known today. Indium is used in alloys and in semiconductor materials as an essential doping agent. Our main research activities are focused on the chemistry of the heavier group 13 elements aluminum, gallium, and indium.
