摘要：

A salicylimine based Al3+ specific fluorescent turn on probe (SB-1) was designed, characterized and evaluated through various spectroscopic techniques. The 1:1 chemical interaction between SB-1 and Al3+ takes place through O-N-O donor sites leading to chelation enhanced fluorescence (CHEF). The lowest detection limit for this measurement was found to be 7.69 x 10(-9) M. The binding interaction of SB-1 with Al3+ was studied through H-1 & C-13 NMR studies, IR as well as through DFT calculations. The HeLa live cells were found to be permeable enough for SB-1 and was able to detect Al3+ inside the cells through confocal microscope. (C) 2016 Elsevier B.V. All rights reserved.
