摘要
采用Alder法合成了3种在苯环对位连接性质不同取代基的卟啉单体和3种桥联基团性质各异的卟啉二聚体,并研究卟啉单体和卟啉二聚体的Z-扫描曲线和光限幅性质.Z-扫描研究结果表明,卟啉测试样品的Z-扫描曲线相似,均出现反饱和吸收和光限幅性质,其中卟啉化合物4的光限幅效果明显,入射光的透过率约为7%.
The authors synthesized three porphyrin monomers with different substituents and three porphyrin dimers with different bridge-linked reagents according to Alder method. The optical limiting properties of the porphyrins were studied via Z-scan and optical limiting properties, and compared with those of other porphyrin molecules under the similar experimental conditions. The Z-scan curves of all the porphyrin samples were similar to each other. The Z-scan curves of all the porphyrin samples showed the characteristics of reverse saturation absorption. Porphyrin 4 had the best optical limiting properties, and the lowest normalized transmittance of porphyrin 4 was 7%.
