Rapid gel-to-sol transition triggered by a photoacid generator under low-power light

Abstract

A photoacid generator as a trigger was introduced into an acid-responsive fluorescent organogel to realize rapid gel-to-sol transition under a low powder light stimulus. The pristine yellow organogel emitted a strong blue-green fluorescence and transformed into a brown solution with emission quenching after irradiation for 20 s by 365 nm light with a light intensity of 0.1 mW/cm2. The yellow gel could be recovered with the addition of triethylamine. Such process could be repeated a few times. This work shows that external photo-responsive molecules can remedy the slow response of gel materials to light irradiation.
