Light induced E–Z isomerization in a multi-responsive organogel: elucidation from 1H NMR spectroscopy†
Abstract
A multiresponsive organogel of (E)-N′-(anthracene-10-ylmethylene)-3,4,5-tris(dodecyloxy)benzohydrazide (I) showed a decrease of fluorescence intensity, decrease in mechanical strength and a change in gel morphology on irradiation with a wavelength of 365 nm. This is attributed to the E–Z isomerization across the CN bond of I as evidenced from 1H NMR spectroscopy.
