| Abstract: | High excimer‐state emission in the H‐type aggregate of a novel asymmetric perylene bisimide derivative, 6 , with triethyleneglycol chains and lactose functionalization was achieved in water. Furthermore, its application for enhancing the visualization of transfer latent fingerprints from glass slides to the poly(vinylidene fluoride) (PVDF) membrane was explored, which showed clear images of the latent fingerprint in daylight and under 365 nm ultraviolet illumination. |
