以蒽醌作为电子受体, 三苯胺作为电子给体, 经过表面活性剂修饰, 得到了一种新型可用于指纹显影剂的表面活性剂有机功能分子C16-TPA-AQ. 该分子在聚集态下发射红色荧光, 具有显著的聚集诱导发光效应. 将其制成了指纹染液, 并通过氯化钾浓度调控聚集程度. 结果表明, 该染液对于附着于不同基底的指纹均有良好的显影效果, 在0.18 mol/L氯化钾调控下得到了三级指纹结构. 此外, 该染液对陈旧指纹也具有显影效果. 由此可见, 该材料在指纹显影领域具有一定应用前景.

An interesting surfactant anthraquinone derivative, named as C16-TPA-AQ, was prepared for fingerprint development by symmetrically introducing strong electron-donating triphenylaniline units. C16-TPA-AQ exhibits significant aggregation-induced emission with red fluorescence in the aggregated state, which could be used to prepare fingerprint developer with its aggregation effectively controlled by potassium chloride concentration. Such developer exerts excellent development effect on fingerprints settled on different substrates with almost no influence of background. By tuning the concentration of potassium chloride to be 0.18 mol/L, level 3 fingerprint details are successfully obtained due to micelle formation and demulsification of surfactants. Besides, the developer is also effective on aged fingerprints. This finding demonstrates the potential of red emission and surfactant aggregation induced emission luminogen (AIEgen) in latent fingerprint development.

Key words: aggregation-induced emission, anthraquinone, surfactant, fingerprint development
