Dual-mode fluorescence switching of photochromic bisthiazolylcoumarin

Author affiliations

Abstract

Three new photochromic coumarins were synthesized. Fluorescence of the open form of 7-hydroxy-3,4-bisthiazolyl-coumarin increased to 1400% by changing the pH only slightly from 6.05 to 7.58. This was subsequently quenched to 1.5% of the maximum intensity at the UV photostationary state in watermethanol media.
