Chemical clustering of a nonemissive and non-AIEgen of Cb-Ph endowed a molecular system (Ad-4CP) with unique dual emissions in the solution state, a typical clustering-triggered emission (CTE), and high emission efficiency in the aggregated state, an aggregation-induced emission (AIE). The CTE was ascribed to intramolecular charge transfer (CT); however, the AIE was ascribed to both intra- and intermolecular CTs. The two-level CTs make the Ad-4CP exhibit remarkable excitation-dependent emissions. We believe that the present work not only delivers a peculiar molecular system with both CTE and AIE properties but also provides an example on how molecular engineering promotes the rational design of CTE and AIE systems via clusterization of suitable structural units.

深入了解基于金刚烷的分子系统所表现出的簇触发发射和聚集诱导发射

Cb-Ph的非发射和非AIEgen的化学聚集赋予了分子系统（ Ad-4CP ）在溶液状态下具有独特的双重发射、典型的聚集触发发射（CTE）以及聚集状态下的高发射效率，聚集诱导发射（AIE）。 CTE 归因于分子内电荷转移 (CT)；然而，AIE 归因于分子内和分子间 CT。两级 CT 使Ad-4CP表现出显着的激发依赖性发射。我们相信，目前的工作不仅提供了一个具有 CTE 和 AIE 特性的独特分子系统，而且还提供了分子工程如何通过合适结构单元的聚类来促进 CTE 和 AIE 系统合理设计的例子。
