Regarding the oscillation of atoms or electrons, Schrödinger utilized the analogy of a cat enclosed within a box to depict the inherent uncertainty . Conversely, for molecular vibrations, the phenomenon can be vividly illustrated through the continuous fluttering of butterfly wings. When compared to the rotor behavior of the RIR mechanism, vibrational behavior necessitates a smaller range of motion and exhibits higher sensitivity. It effortlessly accommodates twisted structures, and diverse configurations confer distinct energy barriers. The majority of the vibrational scaffold is substituted by heteroatoms, whereby subsequent non-covalent interactions present additional dimensions to further restrain the aggregation forces among molecules. A profusion of techniques for structural design and performance regulation can give rise to a broad range of functionalized AIE molecules based on the RIV mechanism. with permission.
