Significant emission enhancement of a bola-amphiphile with salicylaldehyde azine moiety induced by the formation of [2]pseudorotaxane with γ-cyclodextrin†
Abstract
A cationic bola-amphiphile with salicylaldehyde azine moiety exhibited weak emission in water, whereas around 30-fold enhancement of emission was observed upon addition of γ-cyclodextrin due to the formation of [2]pseudorotaxane inclusion complex, which can specifically localize in mitochondria of living cells for fluorescent imaging.
