Hydride elimination from arylpyridyl-boranes results in formation of cationic highly Lewis acidic species. Nature of counterion appears to be crucial for its reactivity but also to its photophysical behavior. By taking advantage of accessibility diverse aryl pyridines and also by hydroboration reactivity of product, we prepared highly emissive compounds exhibiting green-yellow fluorescence with reaching quantum yields up to 93 % have been reported.

芳基吡啶基硼 C，N-螯合物的制备、结构、反应性、路易斯酸性和荧光性质


从芳基吡啶基硼烷中去除氢化物导致形成阳离子高路易斯酸性物质。反离子的性质似乎对其反应性至关重要，而且对其光物理行为也至关重要。通过利用多样化的芳基吡啶的可及性以及产物的硼氢化反应性，我们制备了表现出绿黄色荧光的高发射化合物，其量子产率高达 93%。
