Abstract
⺠A 1,2-bis(thiazolyl) diarylethene for multiphoton-gated photochromism. ⺠Low cycloreversion quantum yield (1.3 Ã 10â3) under continuous excitation. ⺠Time-resolved transient spectroscopy measurements reveal a nonlinear behavior. ⺠Cycloreversion quantum yield: ca. Ã400 up when excited by picosecond laser pulse. ⺠Enhancement due to stepwise two-photon absorption involving S1 and a higher Sn state.
