摘要: Organic second nonlinear optical chromophore GL-COOHs with two carboxyl groups are designed and synthesized in this paper. The structure of characterized by mass spectrum nuclear magnetic resonance spectroscopy. first order hyperpolarizability is studied theoretical calculation, which similar to the famous FTC chromophore. Thanks double group structure, novel side chain polyester electro optic polymers prepared based on GL-COOHs. Their Tgs around 110 °C, high enough for keeping long term stability their activities. Tds above 239 °C, devices preparing process. Else, largest d33 values about 29.3, 43.6 63.1 pm/V polymer GL-S-1, GL-S-2 GL-S-3 respectively. Interestingly, there a linear relation between loading density values.
