摘要 合成并表征了5-(4-乙酰丙氧基)苯基-10,15,20-三苯基卟啉的Yb3+配合物。配合物经元素分析、1HNMR及UV-VIS吸收光谱表征。配合物呈现七配位特征。在可见光的照射下,Yb3+配合物在950—1050nm范围内给出特征发射。配合物在强配位溶剂及非O—H溶剂如二甲基亚砜中的发射强度比在甲醇中的发射强度高近10倍,半衰期也提高两倍。 Ytterbium（Ⅲ） complex of 5-（4-acetylbutyl）phenyl-10,15,20-triphenylporphyrin was synthesized and characterized by 1H NMR,UV-visible spectra and elemental analysis.The complex is seven-coordinate with strong emission between 950—1050nm under visible irradiation.The emission intensity and lifetime of Yb 3＋ complex in DMSO are ten times stronger and two times longer than those in methanol.
