Fluorescent fluorophore was used in various field because of its sensitive property. But conventional fluorophores have aggregation-caused quenching(ACQ) phenomena when they aggregate. So they have some problems to apply on practical applications. To overcome the problems, the opposite method should be introduced that weakly luminescent chromogens in solution state are induced to give high fluorescent signal by the aggregate formation. That is called ‘Aggregation-Induced Emission(AIE)’. Only a limited number of organic fluorescent dyes have been reported as representing AIE characteristics. However, several Kaleidolizine derivatives have low fluorescent intensity in solution state but have high fluorescent intensity in their solid state. AIE probes have ultrahigh imaging contrast, good photostability, and increased intensity with low concentration. Between intramolecular charge transfer (ICT) and restriction of intramolecular rotation (RIR) act as the AIE mechanism in the KIz system. Modification of triphenylphosphonium(TPP) on Kaleidolizine allows successful development of fluorogenic probes for real-time bio-imaging of mitochondria in cells.
