文摘

•: Spectroscopic properties of 1,3-bis(phenylamino)squaraine depend on solvent.
•: In polar protic solvents, rate of radiative process does not depend on viscosity.
•: In polar protic solvents, rate of non-radiative process does not depend on viscosity.
•: 1,3-Bis(phenylamino)squaraine undergoes bimolecular quenching process.
•: Fluorescence quenching rate depends on the structure of quencher and diffusion.
