Two novel pyrene-based isocyanide gold(I) complexes have been designed and synthesized. The different structures lead to distinct and diverse photophysical properties both in solution and in the aggregate state. Multiple photoluminescence, involving monomer emission, locally excited emission and excimer emission, are observed. Notably, an excimer is formed by aggregation in solution and external mechanical stimulation in the solid state, showing aggregation- and mechano-induced excimer emission.
设计并合成了两种新型的基于芘的异腈金（I）配合物。不同的结构导致其在溶液和聚集态下具有独特且多样的光物理性质。观察到多种光致发光现象，包括单体发射、局域激发发射和准分子发射。值得注意的是，在溶液中通过聚集以及在固态下通过外部机械刺激形成了准分子，表现出聚集诱导和机械诱导的准分子发射。
