Linear-dendritic block copolymer hosts for the encapsulation of electro-optic chromophores via H-Bonding



Linear-dendritic block copolymer hosts were synthesized by end-functionalizing poly(methylmethacrylate) with dendrons that acted as hydrogen-bonding acceptors for nonlinear optical chromophores. Second harmonic generation experiments indicate that the d33 coefficients and maximum chromophore loading are increased in linear-dendritic block copolymer hosts over comparable homopolymer hosts. Transmission electron microscopy shows 5–10 nm chromophore domains, confirming the effective spatial dispersion of the chromophores. © 2009 Wiley Periodicals, Inc.
