In order to study the impact of different additional donors on molecular thermal decomposition temperature (Td) value of the chromophores as well as the second polarization (μgβ) value. Three novel materials EFC-OH, EFC-OBu and EFC- OBe were synthesized by attaching additional donors to the benzene ring based on the reported 2-[{4-(4-diethylamino)sty- reneyl}-3-cyano-5,5-dimethyl-5H-furan-2-ylidene]malononitrile (DCDHF-2-V). The three chromophores were characterized by 1H NMR, 13C NHR, FT-IR and elemental analysis. The Td value was determined by TGA testing, and the result showed that three molecules had a good thermal performance. EFC-OBe processing a Td of 278.6 ℃ showed the best among these molecules. The hyperpolarizability was measured and calculated by solvatochromism method. EFC-OBe still showed the best μgβ value of 4.7149×10-44 esu. Comparing to the DCDHF-2-V without additional donors on Td value and μgβ value, additional donors had little effect on Td value while achieved an improvement of one order of magnitude in μgβ values, which indicates that the molecules can work in high temperature and performance better in optics.
