Gated photochromism of 1,2-diarylethenes

Kühni, Joël ; Belser, Peter

In: Organic Letters, 2007, vol. 9, no. 10, p. 1915 -1918

A dithienylethene derivative containing a cyclobutene-1,2-dione skeleton does not exhibit photochromic properties. However, when both ketone functions are protected with cyclic acetal groups, photochromic behavior is observed.
