Abstract
The C4N4 fluorophore is an intense fluorescence emitter featuring a 2,5-diaminopyrimidine core comprising four carbon and four nitrogen atoms. A series of C4N4 derivatives was photochemically dimerized at the 5-amino group, furnishing overcrowded orthotetraaryl-substituted diaryl azo compounds with a characteristic skewed structure revealed by X-ray crystallography. The photo-quenched azo-C4N4s are useful for fluorescently visualizing cells under hypoxic conditions.
