Abstract

Abstract : Cubic NLO properties have been determined for two porphyrin-based polymetallic star-shaped architectures. Abstract : A new Zn(ii ) porphyrin-based dendrimer (52 ) containing twelve Ru(ii ) alkynyl fragments, has been prepared following a convergent approach in two steps from 5, 10, 15, 20-tetra(4-ethynylphenyl)porphyrinatozinc(ii ) (6 ). The cubic nonlinear optical (NLO) properties of52 and other derivatives of6 have been measured by third-harmonic generation (THG) at 1907 nm and by Z -scan over the spectral range 500–1700 nm, revealing the remarkable NLO response of52 in the near-IR range. These results highlight the beneficial role of the extended "cross fourchée"-like polymetallic structure of52 on its third-order NLO properties.
