A novel application of photochromic molecules is to mimic physiological oscillatory calcium signals by reversibly binding and releasing calcium ions in response to light. Substituent changes on the largely unexplored photochromic bisbenzospiropyran scaffold led to significant changes in thermal fading rates in several organic solvents. Excellent correlations have been found between fading rates and empirical Hammett constants as well as calculated ground-state energies. These correlations can be used to improve scaffold design.
Silicon-assisted O-heterocyclic synthesis: Mild and efficient one-pot syntheses of (E)-3-benzylideneflavanones, coumarin-3-carbonitriles / carboxamides, and benzannulated spiropyran derivatives

A new general and efficient method for the one-pot synthesis of (E)-benzylideneflavanones, dibenzospiropyrans and coumarin-3-carbonitriles/ carboxamides is achieved through tandem aldol-cyclocondensation of o-hydroxyaryl carbonyl compounds with aryl aldeh
