A chiral BINOL-bridged imidazole dimer possessing sub-millisecond fast photochromism†
Abstract
We developed a chiral 1,1′-bi-2-naphthol-bridged imidazole dimer possessing 100 μs fast photochromism and high fatigue resistance. It offers great opportunities for the practical applications to fast photoresponsive chiral dopants, invisible security materials and optical trigger molecules to induce the dynamic structural changes in biological matters.
