Abstract
In this study, different generations of a poly(propylene imine) dendrimer have been functionalized with second-order nonlinear optical chromophores. The nonlinear optical properties of these macromols. have been investigated using the hyper-Rayleigh scattering technique. The sensitivity of this technique to mol. symmetry is exploited. The measurements show, in a unique way at the mol. level, that the dendrimers in soln. form globular structures at generations with 32 and 64 4-dimethylaminophenylcarboxamide end-groups with restricted mobility of the end-groups
