We investigate the second-order nonlinear optical properties of a push−pull chromophore in different external and supramolecular environments, through a combined experimental and theoretical approach. In particular, we compare the first hyperpolarizability (\beta) of a model dipolar and polarizable chromophore with that of a charged analogue and of a molecular dimer based on the chromophore itself. We find that the \beta value of the model chromophore in solutions of low-polarity solvents is strongly affected by association effects, already at concentrations of $10^{-3} M$. The presence of a positive charge in close proximity to the chromophore is found to lead to a 100% increase of the β response of the model push-pull chromophore. This ef...
