AbstractA new second-order nonlinear optical (NLO) multi-intramolecular charge-transler chromophore 2.3-bis (4-aminophenyl)-5,6-dicyanopyrazine (DAPDCP) has been desioned and synthesized successfully. It shows that the maximum absorption wavelength lambda(max) of UV/Vis spectrum in 1,4-dioxane is 423 nm and the melting point is above 300degreesC. The doped film of it in PMMA was prepared and poled by corona poling with increasing temperature step by step (5degreesC/min). The second-order nonlinear optical coefficient d(33) is deduced to be 27.2pm/V by the in-situ SHG measurements. The depoling experiments showed that the on-set temperature of the decay of orientation order is 105degreesC which is higoher than that of the typical NLO chromophore N-(4-nitro phenyl)-(s)-prolinol (NPP) doped in PMMA. It has demonstrated again that the harmony of thermal stable-nonlinearility-transparent trade-off can be established by using the designed X-type chromophore with multi-intramolecular charge-transter.
