The construction of boron-element and boron-boron multiple bonds has been a major research focus of the Braunschweig group in the last few years, culminating in the isolation of B-N and B-O triple bond and B-C double bond containing iminoboryl, oxoboryl and alkylideneboryl complexes of platinum, as well as in the synthesis of diborenes and diborynes, the all-boron analogues of alkenes and alkynes. In the course of this work we were able to coordinate diborenes and diborynes to coinage metal centers and found the resulting complexes to be highly luminescent. Whereas copper(I) and silver(I) complexes of diborenes exhibit fluorescence in unusually high quantum yields of 0.18-0.95 with lifetimes of a few nanoseconds, a diboryne with three CuCl coordinated to it shows intense emission on the microsecond timescale, indicating the luminescence to be phosphorescence in nature.This project aims at the investigation and understanding of the photophysical properties of diborene and diboryne transition metal complexes. The proposed work represents the first foray of our groups with such lab curiosities into the field of materials science, exploring these fundamentally new classes of compounds in order to develop them further and make them available for applications which exploit photoactive materials.

在过去的几年中，硼元素元素和硼 - - 波隆多键的构建一直是Braunschweig组的主要研究重点烯烃和炔烃的类似物。在这项工作的过程中，我们能够将二苯乙烯和二尖齿与固定金属中心进行协调，并发现所得的配合物具有很高的发光。而二苯甲酸苯甲酸的铜（i）和银（i）复合物的异常高量子产率为0.18-0.95，其寿命为几个纳米秒，三个diboryne，三个Cucl协调的diboryne，它在微观时光尺度上表现出强烈的发射，这表明在插曲中，呈量化的态度。 Diborene和Diboryne过渡金属复合物的光物理特性。拟议的工作代表了我们小组的第一次企业，具有这样的实验室好奇心进入材料科学领域，探索了这些从根本上新的化合物，以便进一步开发它们，并使其可用于利用光活动材料的应用。
