摘要
合成了meso-四(对-酰氧基苯基)卟啉铂配合物。采用UV-Vis、1HNMR、MS、光致发光光谱、DSC、热台偏光显微镜等分析测试技术对化合物的结构和性能进行了表征。结果表明,配合物在660nm附近有较强的三线态发射,磷光量子效率在0.183～0.211之间,三线态寿命为8.86～13.52μs。表明在卟啉铂meso位上连接长链酰氧基后,能够降低三线态寿命,减少配合物分子间的相互作用。同时长链酰氧基的引入赋予配合物液晶性质。这类卟啉铂配合物有望用作有机电致发光器件和线偏振发光器件的磷光材料。
Three meso-tetrakis（4-n-acyloxylphenyl） porphyrins and their platinum（Ⅱ） complexes were synthesized.The structures of the compounds and photophysical properties were characterized by ^1H NMR,MS,UV-Vis and photoluminescence（PL） spectroscopies.Differential scanning calorimetry（DSC） and polarizing microscope were used to probe liquid properties of the complexes.Strong triplet emission peaks at around 660 nm were observed with phosphorescence quantum efficiencies（0.183～0.211） in THF solution and triplet lifetime（8.86～13.52 μs） in degassed CH2Cl2 solution.The results show that the attached acyloxy of the long carbon chains at the meso-positions of tetrakis（4-hydroxylphenyl） porphyrin can reduce phosphorescent lifetime and aggregation between molecules.Further,these complexes reveal characteristic of liquid crystal for long carbon chain acyloxy at the meso-positions of porphyrin complexes.It is possible that these new complexes can be used as applicable phosphorescent emitters in organic light emitter devices（OLEDs） and polarized luminescent devices.
