在这个角度来看，我们强调了许多例子的光致发光金属配合物支持的异氰化物，重点是最近的发展，包括几个从我们自己的小组。在这一领域的工作表明，异氰化物可以发挥重要的结构作用，无论是作为一个终端配体和作为一个桥接配体的多核结构，并可以影响激发态的字符和激发态动力学。此外，有许多异氰化物负载的络合物的实例，其中异氰化物用作发色配体，这意味着在光化学中重要的低能激发态部分或完全位于异氰化物上。最后，在发光化合物的设计中出现的趋势是使用异氰化物作为亲电前体，通过亲核加成转化为无环卡宾，这赋予某些物理学优点。本透视图旨在展示异氰化合物在发光化合物设计中所扮演的不同角色，展示导致光致发光相关基础知识，功能和应用大幅增长的最新发展。
In this Perspective, we highlight many examples of photoluminescent metal complexes supported by isocyanides, with an emphasis on recent developments including several from our own group. Work in this field has shown that the isocyanide can play important structural roles, both as a terminal ligand and as a bridging ligand for polynuclear structures, and can influence the excited-state character and excited-state dynamics. In addition, there are many examples of isocyanide-supported complexes where the isocyanide serves as a chromophoric ligand, meaning the low-energy excited states that are important in the photochemistry are partially or completely localized on the isocyanide. Finally, an emerging trend in the design of luminescent compounds is to use the isocyanide as an electrophilic precursor, converted to an acyclic carbene by nucleophilic addition which imparts certain photophysical advantages. This Perspective aims to show the diverse roles played by isocyanides in the design of luminescent compounds, showcasing the recent developments that have led to a substantial growth in fundamental knowledge, function, and applications related to photoluminescence.
