芴与炔丙基溴在NaOH/PhCH2N+Me3C l催化作用下反应生成85%的二炔丙基芴(DPF).在10-4Pa真空中的ITO玻璃基板上沉积DPF制成EL器件.测得DPF特有的紫外可见吸收波段为337nm和354nm,其在432nm的蓝色光致发光(PL)光谱对应的光子能量是2.87eV.二炔丙基芴电致发光(EL)器件具有典型的矫正二极管性能,蓝色的电致发光光波以及12V的开启电压.由光谱扫描色度计PR-705测得色度值为(0.16,0.17),意味着器件发深蓝光.通过微分扫描热量计和热解重量分析仪研究DPF的热反应性能,其熔点和反应温度分别为117℃和247℃.
Fluorene and propargyl bromide were reacted under the catalysis of NaOH / PhCH2N + Me3Cl to produce 85% of diproparnylfluorene (DPF). DPF was deposited on an ITO glass substrate in a vacuum of 10-4 Pa to produce an EL device. DPF’s unique UV-visible absorption band is 337 nm and 354 nm, which corresponds to a photon energy of 2.87 eV at a blue photoluminescence (PL) spectrum at 432 nm. Di-propargylfluorene electroluminescent (EL) devices have typical diode correction performance , The blue electroluminescent light and the turn-on voltage of 12 V. The chromaticity value (0.16, 0.17) as measured by a spectral scanning colorimeter PR-705 means that the device is dark blue in color. By differential scanning calorimeter and pyrolysis The gravimetric analyzer was used to study the thermal reactivity of DPF. The melting point and reaction temperature were 117 ℃ and 247 ℃, respectively.
