New fluorogenic enzyme substrates were synthesized by the coupling of aminonaphthalenesulfonamides or 6-hydrazinobenz[de]isoquinoline-1,3-diones with beta-alanine. The 6-hydrazinobenz[de]isoquinoline-1,3-diones were also condensed with a range of aryl aldehydes to give the corresponding hydrazones. The photophysical properties of the synthesized amines and hydrazines and their amide, hydrazide and hydrazone derivatives, were examined and they were also incorporated into Columbia agar in order to determine their potential for the detection of pathogenic bacteria.

A general strategy for in situ assembly of light-up fluorophores via bioorthogonal Suzuki-Miyaura cross-coupling
either photochemically or spontaneously transformed into highlyfluorescent rearrangement products with remarkable photophysical properties including significant fluorescence enhancement, large Stokesshift, high fluorescence quantum yield, superior photostability, and distinct solvatochromic effect. This strategy is suitable for selective labeling of diene-modified proteins and visualizing specific organelles
