摘 要:研究了一系列卟啉化合物不同浓度下的荧光强度 ,发现卟啉苯环取代基α与其最大荧光强度 (Fmax) ,荧光效率Ψ有良好的线性关系。同时随着卟啉浓度的增加或者取代基常数的减小 ,6 5 0nm附近的荧光发射峰波长均发生红移。 |

CHU Ming-fu; et al.(College of Chemistry and Chemical Engineering; Hunan University; Changsha; 410082; China) |
Abstract:The fluorescence strength of series of porphyrin with different substituent were investigated.A linear relationship between the substituent constant ,F max ,and fluorescence efficiency φ was found,Red fluorescence wave becoming longer with porphyrin concentration increasing or substituent constant decreasing was also discussed. |
Key words:porphyrin; fluorescence; linear relationship wavelength increasing |
