Abstract
Tetrathiafulvalene (TTF) derivatives with diarylethene moieties have been s ynthesized. A derivative having 2,4,5-trimethylthiophene rings as the aryl groups showed photochromism, while a derivative with 2, 5-dimethylthiophene rings did not show any color change by UV irradiation. The different react ivity was ascribed to the difference in the conformation of thiophene rings in the two derivatives.
