Organic solid state vapochromic materials are of great significance for the development supramolecular chemistry and science. Herein, we synthesize a crown ether derivative (An34C10) containing two anthracene units construct new ether-based host-guest co-crystals. Due to presence anthracene, An34C10 not only shows good fluorescence properties but also displays mechanochromism. Single crystal structural analysis, powder X-ray diffraction differential scanning calorimetry experiments demonstrate that transformation between different stacking modes is responsible In addition, can complex with 1,2,4,5-tetracyanobenzene (TCNB) form (An34C10@TCNB) Because organic solvent fuming alters charge-transfer interactions in An34C10@TCNB, co-crystals be turned on off by 4-methylpyridine chloroform vapors, respectively, realizing selective detection opposite emission outputs. Meanwhile, stimuli-responsive An34C10@TCNB possess cycling performance. This work provides strategy construction luminescent materials.
