硼-元素和硼-硼多重键的构建是布伦瑞克研究组近年来的一个主要研究热点,其研究成果包括含B-N、B-O三键和B-C双键的亚氨基硼基、氧代硼基和亚烷基硼基铂配合物的分离,以及烯烃和炔的全硼类似物二硼烯和二硼炔的合成。在这项工作的过程中,我们能够协调diborenes和diborynes钴金属中心,并发现所得的配合物是高度发光。尽管二硼烯的铜(I)和银(I)络合物以0.18-0.95的异常高的量子产率显示荧光,寿命为几纳秒,但具有三个CuCl配位的二硼炔在微秒时间尺度上显示强烈的发射,本计画旨在研究二硼烯与二硼炔跃迁的电子物理性质金属配合物这项拟议的工作代表了我们的团队首次涉足材料科学领域,探索这些全新的化合物类别,以便进一步开发它们,并使它们可用于利用光活性材料的应用。
英文摘要
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.
