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起着重要作用。除了铝作为块体金属和合金中的组分明显存在之外，有机金属铝烷还间接以聚合物（齐格勒/纳塔型聚合）和电子器件（化学气相沉积，CVD）的形式存在。对有机金属铝化合物的基本知识的缺乏与该元素的重要性形成了鲜明对比。镓是现代电子器件中的关键成分;例如，GaAs是当今已知的第二大半导体。铟在合金和半导体材料中用作重要的掺杂剂。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。

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.
