摘　　要：Novel types of photoresponsive organogelators containing a diazocine moiety have been synthesized,and their gelation behaviors have been characterized systematically.Subtle changes in the pendant structure of these bent-core molecules cause significant changes in the molecular packing mode in their self-assembled gels.By making use of the unconventional conformational and photochromic properties of the diazocine core,the obtained gels exhibited excellent photoswitching and-chromic properties.For the first time,the diazocine unit has been demonstrated as a versatile building block to construct photoresponsive supramolecular gels.The sensitive interconversion between multiple states of these chromic gels highlights their promising applications in fabricating logic gates with appropriate addressing mode(stimulated by visible light or heating).
