摘　　要：采用微波辐射方法,合成了一种新型的卟啉-蒽醌二元化合物,通过红外光谱、紫外-可见光谱、1HNMR对新化合物的结构进行了表征。探讨了蒽醌引入对化合物光谱性质的影响。吸收光谱显示:蒽醌引入扩大了化合物的共轭体系,紫外-可见吸收红移;荧光光谱表明:卟啉与蒽醌通过酰胺键连接形成共轭体系利于卟吩环激发态电子向蒽醌转移,导致荧光猝灭。A novel porphyrin-anthraquinone compound was synthesized under microwave radiation. The structure of new compounds have been confirmed by IR, UV-visible spectrum, 1HNMR. The influence of structure to spectral property were discussed. The results indicated ultraviolet-visible absorption shifted to red due to anthraquinone connected to the porphyrin molecules to expand the conjugated system of the compounds. Fluorescence spectra show that porphyrin and anthraquinone via amido link form a conjugated system. Thus, the excited state photoelectron in porphin ring transfer to the anthraquinone ,resulting in fluorescence quenching.
