A two-photon probe for Al(3+) in aqueous solution and its application in bioimaging
A salicylimine probe L with a simple structure has been researched more in-depth on fluorescence sensor properties based on two-photon (TP) absorption. L displays excellent selective turn-on fluorescence response for Al(3+) in hexamethylenetetramine-buffered (HMTA) aqueous solution (0.3M, pH=5.8) un...

| description | A salicylimine probe L with a simple structure has been researched more in-depth on fluorescence sensor properties based on two-photon (TP) absorption. L displays excellent selective turn-on fluorescence response for Al(3+) in hexamethylenetetramine-buffered (HMTA) aqueous solution (0.3M, pH=5.8) under one-photon (OP) excitation. With the help of OP fluorescence, TP fluorescence titration, UV-spectra titration and Job's plot, the stoichiometric ratio of L with Al(3+) was determined to be 1:1. The coordination sites and the coordination mechanism of L with Al(3+) were analyzed in detail through (1)H NMR data. Not only with a detection limit of 5.2×10(-9)M in vitro, but also the probe has been successfully used in the live cells and tissues for the imaging of Al(3+) with TP fluorescence microscopy due to the enlarged TP cross section, providing a novel testing method for measuring Al(3+) in solution or cell tissue with low autofluorescence and cytotoxicity. |
