Construction of stimuli-responsive assembled structures has attracted significant attention for their applications in sensing, information storage and optoelectronic devices. The important reason is that supramolecular structures with different shapes and sizes display different electronic, optical, and catalytic properties. Considering a balance between steric constraints and noncovalent interactions such as hydrogen bonding and pi-pi stacking interactions, we have designed AIEE-active trigonal azobenzene-based molecules with various substituents. We have investigated how molecular structures and assembly environments are correlated with their assembled structures and functions. Diverse fluorescent organic materials such as spheres, rods, fibers, and helical structures are constructed depending on substituents and solvent environments. Light- and pressure-induced fluorescence response and morphological transition have been confirmed with OM, LCM, SEM, and FOM measurements. |
