Guest-host cooperativity in organic materials greatly enhances the nonlinear optical response
JOURNAL OF PHYSICAL CHEMISTRY C, 112:4355-4363, MAR 20 2008
Some of the most highly active organic electro-optic (EO) materials developed recently rely on the combination of an EO-active (chromophore-containing) host material (dendrimer or side-chain polymer) and an EO-active (chromophore) guest. These new binary-chromophore materials exhibit EO coefficients (r(33)) in the range of 250 to greater than 300 pm/V (currently as high as 450 pm/V). The EO activity of these binary-chromophore materials is greater the sum of their individual components. 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.
