Dendritic electro-optic materials have been recently introduced as a method for the control of inter-chromophore electrostatic interactions to realize large nonlinear optical response. Hexakis(4-carboxyphonoxy)cyclotriphosphazene bearing six nonlinear optical chromophore which has phenylenevinylene bridge with long-chain alkoxy group and tricyanofuran as electron-acceptor was prepared. For the comparison of their effect of flexiblilty in the NLO property, another compound with diethoxy group as spacer was synthesized, because hexakis(4-carboxyphonoxy) cyclotriphosphazene was so rigid. The chemical, physical and optical properties will be discussed. |
