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
