Terpyridine Zn(II), Ru(III) and Ir(III) complexes as new asymmetric chromophores for nonlinear optics: first evidence for a shift from positive to negative value of the quadratic hyperpolarizability of a ligand carrying an electron donor substituent upon coordination to different metal centres / D. Roberto, F. Tessore, R. Ugo, S. Bruni, A. Manfredi, S. Quici. - In: CHEMICAL COMMUNICATIONS. - ISSN 1359-7345. - :8(2002), pp. 846-847.

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.
