Mercury ion induced activation of the C—O bond in a photo-responsive spiropyran

摘要

The conversion of 7-hydroxy-BIPS in solution from colourless form to colored form can be induced using both light and the addition of Hg~(2+) ion. No significant color change is observed when other ions (Ca~(2+), Mg~(2+), Zn~(2+), Cd~(2+), Co~(2+), Cu~(2+), Mn~(2+), Fe~(2+), Ni~(2+), Pb~(2+), K~+, Na~+, Li~+, and Ag~+) were used.
