通过Suzuki缩聚方法,将单体2,7-二溴-9,9’-二-(3,6-二氧烷基)芴和9,9’-二辛基芴-2,7-二-(三亚甲基硼酸酯)合成了一种新型的蓝光材料-双亲芴基共聚物。采用1H NMR1、3C NMR和元素分析对共聚芴结构进行了表征;通过GPC、DSC和TGA测试,共聚芴有较高的分子量和较窄的分子量分布,同时还有很好的热稳定性。对共聚芴的紫外吸收光谱分析表明,在甲苯溶液和薄膜中的波长分别为389nm和393nm;对共聚芴的荧光发射光谱分析表明,在甲苯溶液和薄膜中的波长分别为415nm和437nm。
The monomers 2,7-dibromo-9,9’-di- (3,6-dioxanyl) fluorene and 9,9’-dioctylfluorene-2,7-di- (Trimethylene Borate) A Novel Blu-ray Material - Amphiphilic Fluorene Copolymer was synthesized. Copolyfluorene structure was characterized by 1H NMR1,3C NMR and elemental analysis. The copolymerization fluorene had higher molecular weight and narrower molecular weight distribution by GPC, DSC and TGA, and also had good thermal stability. UV-Vis spectra of copolymerization fluorene showed that the wavelength in toluene solution and film were 389nm and 393nm, respectively. The fluorescence emission spectra of copolyfluorene showed that the wavelength in toluene solution and film were 415nm and 437nm, respectively.
