Abstract

Abstract A series of water-soluble 1-amino-naphthalenes and 2-amino-fluorenes are prepared. These serve as model fluorophores for measuring the thermodynamics and kinetics of fluorescence quenching with phenylboronic acids and aliphatic amines. Steady- state and time-resolved fluorescence quenching kinetics are investigated using the Stern– Volmer method. Diffusion limited quenching constants and exergonic thermodynamics of ...
