Fabrication and photochromism of high-density diarylethene monolayer immobilized on a quartz-glass substrate

Diarylethene monolayer was fabricated on a quartz-glass substrate using a silane coupling technique. The coupling agent was easily prepared from a diarylethene with a hydroxy group and 3aminopropyltriethoxysilane. It was found that the chromophore was introduced in high density on the substrate and still exhibited reversible photochromism with relatively high conversion upon, photoirradiation, despite being constrained on the quartz-glass surface.
