Abstract
The synthesis of 4′-(C6H4-p-NBu2)-2,2′:6′, 2″-terpyridine and the strongly enhanced second-order NLO response of its Zn(II), Ru(III) and Ir(III) complexes are reported, evidencing for the first time a shift from positive to negative value of the ligand quadratic hyperpolarizability by varying the nature of the metal centre.
