Mononuclear aluminum complex derived from 1,1,1,1-tetrakis[(2- salicylaldiminomethyl)]methane acting as a zinc sensor: Crystal structure, emission and lifetime studies

The mononuclear complex [AlHL] (1) has been prepared using AlCl 3, H4L and triethylamine in a 1:1:3 ratio (H4L = 1,1,1,1-tetrakis[(2-salicylaldiminomethyl)]methane). [Al(HL)] crystallizes in the monoclinic space group P2(1)/c. Although H4L does not emit at room temperature, a remarkable CHEF (Chelation Enhancement of Fluorescence Emission) effect is observed upon the formation of the complex [Al(HL)] (1). When excited at a wavelength of 350 nm, complex 1 emits at 433 nm. Blue emitting aluminum complexes find special importance as far as OLEDs are concerned and complex 1 is one of the best blue emitting compounds to the best of our knowledge. Emission titration of a solution of complex 1 in acetonitrile with Zn2+, Cd2+, Hg2+ and Pb2+ shows selectivity towards the Zn2+ ion. Unlike Cd2+, Hg 2+ and Pb2+, which quench the emission, Zn2+ enhances the fluorescence intensity by 1.64-folds. The quenching process follows the Stern-Volmer equation and in order to get an insight of whether the quenching is static or dynamic in nature, lifetime measurements were carried out. Interestingly, mercury was found to follow static quenching, while cadmium, lead and nickel adopted dynamic quenching pathways.

Multiple metal coordinating behaviour of the tetrapodal ligand 1,1,1,1-tetrakis[(salicylaldimino)methyl]methane

The tetrapodal ligand 1,1,1,1-tetrakis[(salicylaldimino)methyl]methane (H4tsam) has been introduced for the first time for metal complexation. Two zinc(II) complexes[Zn2(tsam)] (1) and [Zn 3(Htsam)2]?2C7H8 (2) have been obtained by reacting zinc acetylacetonate with the ligand in the presence of triethylamine, while a cobalt(III) complex [Co(Htsam)]?CH 3CN?H2O (3) is obtained when Co(ClO4) 2?6H2O is reacted in air. All the compounds have been characterized by their elemental analyses and ESI-MS, IR, UV-VIS and 1H NMR spectra. The X-ray crystal structures of H4tsam, 2 and 3 have been determined. Compounds 1 and 2 exhibit fluorescence in solution and the lifetimes of their luminescence decay have been measured. Thermal analysis (TGA, DTA) of 2 with regard to loss of encapsulated toluenes and redox behaviour of 3 have been studied.
