compound (probe 1) has been designed and synthesized. The colorimetric and fluorescent properties of probe 1 towards various amino acids were investigated in detail. Specific colorimetry and fluorescence response of probe 1 for thiols were found in PBS buffer solution, which can be deduced to a reaction of thio-promoted conjugate addition/cyclization sequence between probe 1 and thiols. The probe 1 can
