TL;DR: The results of these studies provide insight into the complicated effects on molecular hyperpolarizability of substituting heteroaromatic subunits into the donor group structures and ab initio DFT generated beta(0;0,0) is effective as a predictor of changes in r33 behavior based on chromophore structure modification.

TL;DR: These results provide new insight into the ordering behavior of EO dendrimers and demonstrate that the frequently observed asymptotic dependence of electro-optic activity on chromophore number density may be overcome through rational design.

TL;DR: The experimentally observed increase in the nonlinear optical response of two representative classes of EO chromophore−EO dendrimer and EO Chromophore+EO polymer mixtures relative to the response of the isolated components is described quantitatively herein by a physical model that accounts for cooperativity in the guest−host interactions.

TL;DR: Theoretical guidance based on correlated real-time, time-dependent density functional theory (RTTDDFT) quantum mechanical and pseudo-atomistic Monte Carlo molecular dynamical (PAMCMD) statistical mechanical computational methods have led to dramatic (exceeding a Moore's rate) improvement in molecular and macroscopic optical nonlinearity as discussed by the authors.

TL;DR: In this paper, correlated quantum and statistical mechanical calculations are required to understand the dependence of macroscopic electro-optic activity upon chromophore structure and intermolecular electrostatic interactions.
