几个蓝色发光化合物分子设计及合成

Molecular design and synthesis of several blue light-emitting compounds

设计并合成了4个新的具有1,3-二芳基5-(α-呋喃基)吡唑啉母体结构的化合物,采用红外光谱(IR)、核磁共振氢谱(1 H-NMR)和质谱(MS)对其结构进行了确证。进而测定了化合物的液体及固体荧光激发、发射光谱,在10-6mol/L的溶液中都具荧光性质,化合物Ⅱ、Ⅲ和Ⅳ具有良好的固体荧光发光能力。化合物Ⅲ和Ⅳ在空气中稳定性好,其固、液体发光的最大发射波长都在450nm附近,半峰宽较窄,具有色纯度好,可望在电致发光和光致发光方面加以应用。

Four new pyrazoline compounds with 1,3-diaryl-5-（α-furyl） parent structure were designed and synthe- sized. Using infrared speetroseopy（IR）, NMR（1 H-NMR） and mass spectrometry（MS） confirmed their structures. Further, liquid and solid fluorescence excitation and emission spectra of compounds were measured,all the compounds showed good fluorescence properties in the 10-6 mol/L. Compounds Ⅱ , Ⅲ and Ⅳ showed good fluorescence emission capability in solid state. The maximum emission wavelength of compounds Ⅱ and Ⅳ in solid and liquid were in the vicinity of 450nm with nar- row half-peak width,good color purity and good stability in air. they were hope be applied in aspects of electroluminescence and photoluminescence.
