Universidad de Zaragoza (orcid)0000-0002-3206-9868 Multichromophoric calix[4]arenes: Effect of interchromophore distances on linear and nonlinear optical properties 2012 Access copy available to the general public Unrestricted Multichromophoric calix[4]arenes with two or four disperse red one (DR1) moieties linked to the lower rim have been synthesized. The second-order nonlinear optical activity was measured by using the electric-field-induced second-harmonic generation technique and there was a nearly linear increase of the μβ value with the number of chromophores in the molecule without affecting the charge-transfer absorption wavelength. The effect that the number of DR1 units plays on the hyperpolarizability, the dipole moment, and the absorption maxima has been also studied by using quantum chemical calculations. It was found that it was necessary to synthesize multichromophores with distant chromophores to obtain large nonlinear optical responses. info:eu-repo/semantics/openAccess All rights reserved http://www.europeana.eu/rights/rr-f/ 3.349 2012 PHYSICS, ATOMIC, MOLECULAR & CHEMICAL 7 / 34 = 0.206 2012 Q1 T1 CHEMISTRY, PHYSICAL 42 / 134 = 0.313 2012 Q2 T1 info:eu-repo/semantics/article info:eu-repo/semantics/acceptedVersion Franco, S.
