Popis: | Small molecules possess large two-photon action cross sections (Φσ) are highly demanded for biological purpose. Herein, three novel terpyridine containing flexible amino diethylacetate organic small molecules (A1, A2 and A3) were rationally designed and their photophysical properties were investigated both experimentally and theoretically. The results revealed that the three chromophores possess large Φσ and remarkable Stokes' shift in high polar solvents, which are particularly benefit for further biological imaging application. One chromophore (A1) displayed an effective intracellular uptake against lung cancerous living cells A549. Colocalization studies suggested the internalized subcellular compartment was mitochondria. Consequently, chromophore A1 provides a promising platform to directly monitor mitochondria in living cells under two-photon confocal laser scanning microscopy. |
