On-demand acid-gated fluorescence switch-on in photo-generated nanospheres
DOI: 10.1039/D0CC01557A, Communication
Polymer particles are synthesized using a photo-active ortho-methyl benzaldehyde with a terminal alkyne for cross-linking. The reactive 1,4-dihydronaphthalene at every cross-linking point undergoes aromatisation to a fluorescent naphthalene upon exposure to acid.
