Photomodulated white light emission in hydrogel. a A general schematic showing photocyclization of TPE (tetraphenylethene) to DPP (diphenylphenanthrene) on irradiation with 365 nm light. b The emission spectrum of Rh6G0.08%@MOC-G5 before photoirradiation (black), after 5 min (red) and 9 min (blue) irradiation with 365 nm light source. c Schematic showing the energy transfer pathways before and after photoirradiation. The corresponding CIE coordinates of Rh6G0.08%@MOC-G5 and white-light-emitting gel (Rh6G-DPPQA@MOC-G5) are mentioned below the respective hydrogel images. d Chromaticity diagram showing corresponding CIE coordinates of MOC-G5 (black), Rh6G0.08%@MOC-G5(pink), white-light-emitting hydrogel (red, form after 5 min of photoirradiation on Rh6G0.08%@MOC-G5), hydrogel (navy blue, form after 9 min of photoirradiation on Rh6G0.08%@MOC-G5) and Rh6G (wine). e A glass slide coated with MOC-G5 hydrogel is irradiated with 365 nm light to write ‘JNC’. Processability of white-light-emitting hydrogel: f image of glass substrate coated with white-light-emitting hydrogel under UV lamp, g writing and h painting using same hydrogel on 365 nm UV lamp. i, j Images of a flexible plastic substrate (5 × 3 cm) coated with white-light-emitting-hydrogel under UV light and k under day light
