Fig. 1: Photodissociation property of PhoCl1 and generation of red fluorescence through photoexposure to 405 nm light.
From: Photoinduced chromophore dissociation resulting in aggregation-induced red fluorescence
A Model of photodissociation of PhoCl1 with a built-in chromophore, p-HBI, within its barrel structure (represented as a cylinder with green emission), B Visual images of PhoCl1 acquired under a UV transilluminator (λ = 365 nm) at different timepoint of unexposed and exposed PhoCl1.Upon photoexposure PhoCl1 solution transitions from green to orange-red C Absorption spectra of PhoCl1 before (Green solid line) and after (Red solid line) exposure to 405 nm light for 12 h. D Fluorescence spectra of PhoCl1 before (Green solid line) and after (Red solid line) exposure to 405 nm light, and (E) The change in the fluorescence (λex = 400 nm, λem = 510 nm) of unexposed PhoCl1 (control) and 405 nm LED exposed PhoCl1 (photocleaved mixture) up to 6 h. Black circles are exposed PhoCl1 fluorescence decay, while the green solid line is unexposed PhoCl1 fluorescence. Relative Fluorescence Units (RFU) have been used as a measure of concentration.
