α-蒎烯衍生物发光配体的合成及性能研究

Synthesis and Properties of α-Pinene Novel Electroluminescence Materials

以α-蒎烯为原料,制备3种新型有机发光材料。由α-蒎烯合成桃金娘烯醛后,分别与邻氨基苯酚、邻苯二胺、邻氨基苯硫酚缩合得到3种α-蒎烯衍生物的发光配体,即:(1-苯并噁唑)-α-蒎烯,(1-苯并咪唑)-α-蒎烯,(1-苯并噻唑)α--蒎烯。以四氢呋喃为溶剂,对它们的光谱性能进行了测试。1-(苯并噁唑)-α-蒎烯的最大吸收峰为466nm,最大发射波长为441 nm,呈黄色光;1-(苯并咪唑)-α-蒎烯的最大吸收峰为299 nm,最大发射波长为384 nm,呈蓝绿色光;1-(苯并噻唑)-α-蒎烯的最大吸收峰为302 nm,最大发射波长为368 nm,呈蓝绿色光,可作为发光材料应用于有机电致发光器件中。

Three novel organic electroluminescence materials,i.e.,1-benzoxazolyl-α-pinene,1-benzimidazolyl-α-pinene,and 1-benzothiazolyl-α-pinene,were synthesized by the oxidation of α-pinene to myrtenic aldehyde,followed by the condensation with 2-aminophenol,1,2-phenylenediamine,and 2-aminothiophenol,respectively.The results indicated that 1-benzoxazolyl-α-pinene gave a strong yellow emission with a peak at 441nm and its UV-visible spectrum peak was at 466nm,1-benzimidazolyl-α-pinene emitted a strong blue-green fluorence with a peak at 384nm and the maximum UV-visible wavelength was at 299nm,and 1-benzothiazolyl-α-pinene showed a strong blue-green light with emission peak at 302nm and its UV-visible spectrum peak was at 368nm,which made them luminescent materials in OLEDs.
