Efficient green-red piezofluorochromism of bisanthracene-modified dibenzofulvene†
Abstract
A general approach for the synthesis of dibenzofulvene-based derivatives is demonstrated. The bisanthracene modified dibenzofulvene (F-DAn) exhibits efficient piezofluorochromic properties with the fluorescence reversibly altered between green (536 nm) and red (620 nm) under external stimuli.
