The simple Schiff base (Z)-N-benzylidenenaphthalen-1-amine (L) acts as an effective fluorescence sensor for Al(3+) by "off-on" mode, and ca. 42 times enhancement in fluorescence intensity is observed. The detection limit of L towards Al(3+) is observed to be 5 × 10(-5) M. UV/Visible and fluorescence data as well as DFT calculations confirm 1:3 coordination between Al(3+) and L through N atoms in a pyramidal shape. L is employed for imaging the Al(3+) ion in living biological cells and for the determination of the Al(3+) ion in bovine serum albumin.
简单席夫碱（Z）-N-苄叉萘-1-胺（L）通过“关-开”模式作为铝离子（Al(3+)）的有效荧光传感器，荧光强度增强约42倍。观察到L对Al(3+)的检测限为5×10(-5) M。紫外可见光谱和荧光数据以及密度泛函理论计算证实Al(3+)与L通过氮原子以金字塔形状形成1:3配位。L用于对活体细胞中的Al(3+)离子进行成像以及测定牛血清白蛋白中的Al(3+)离子。
