A single-state molecule compound with phenanthrene-imidazole as fluorescent core was synthesized. The compound emitted white light in solid state and exhibited aggregation induced emission enhancement (AIEE) characteristic in solution state. From photophysical properties, it was presumably that π-π stacking caused by the excimer, which generated between solid molecules, led to the emitting white light. In addition, in the solution state, with the increasing fraction of the poor solvent, the rotation of the compound molecule was inhibited, which led to the luminescence enhancement induced by aggregation. In the aspect of Pd⁰ response, compound 6 had a sensitive detection of Pd⁰. The bathochromic shift of emission peak from around 390 nm to around 425 nm and remained saturated within 30 min. Compound 6 was stable at pH of 6–9 and the detection limit for metallic palladium was as low as 2.7 nM.

合成了以菲-咪唑为荧光核的单态分子化合物。该化合物以固态发射白光，并在溶液状态下表现出聚集诱导的发射增强（AIEE）特性。从光物理性质来看，推测是由于在固体分子之间产生的受激准分子引起的π-π堆积导致了发射白光。此外，在溶液状态下，随着不良溶剂比例的增加，化合物分子的旋转受到抑制，从而导致聚集引起的发光增强。在Pd ⁰响应方面，化合物6对Pd ^0的检测很灵敏。。发射峰的红移从大约390 nm到大约425 nm，并在30分钟内保持饱和。化合物6在6-9的pH值下稳定，金属钯的检出限低至2.7 nM。
