Acridinediones, a new addition to the family of dyes having aggregation induced emission characteristics have been reported. Facile hydrophobic interactions between the acridinedione aggregates and fingerprint residues were exploited to lift the latent fingerprint marks on a non-porous substrate. By employing this preferential adhesion approach, a portable wet method for the enhancement and visualization of latent fingerprint marks using hand held UV light and mobile camera was demonstrated. Using this simple, rapid, cost effective, eco and user friendly method the latent fingerprints, its primary and secondary level of information’s can be easily decoded. These acridinedione derivatives also show strong blue luminescence in solid state with high fluorescence quantum yield.

据报道，cri啶酮是具有聚集诱导发射特性的染料家族的新成员。利用cr啶二酮聚集体和指纹残基之间的便捷疏水性相互作用来提升无孔底物上的潜在指纹标记。通过采用这种优先的粘附方法，展示了一种便携式湿法，用于使用手持UV灯和移动相机来增强和可视化潜在的指纹标记。使用这种简单，快速，具有成本效益，生态和用户友好的方法，可以轻松解码潜在指纹，其主要和次要信息级别。这些a啶二酮衍生物还以高荧光量子产率显示出固态的强蓝色发光。
