Thermal and Photochemical Properties of 4,7-Dihydroxyflavylium in Water-Ionic Liquid Biphasic Systems: A Write-Read-Erase Molecular Switch

摘要

In the framework of supramolecular chemistry,synthetic flavylium salts can be envisaged as molecular systems that exist in different forms (multistate),which can be interconverted by different external stimuli (multifunctional).Herein we explore a new dimension brought by ionic liquids to flavylium chemistry.
