| 摘 要： | The linear correlations of Hammett constants with the 0-0 transition energies, and the ratios of the oscillator strength are used to probe the conjugation interactions between π-electron of macrocy-cles and metal ion of complexes with the substituents on m-position of benzene ring for the asymmetric pen-taazadentate porphyrin-like compounds. The absorption and fluorescence spectra appear on λmax> 750 nm and 769 nm near-IR regions respectively. The quantum yields and lifetimes of fluorescence are about 10-2and less than 1 ns respectively. The T1--Tn transient absorption spectra appear on 487-496 nm and thequantum yields for generating singlet oxygen are as high as 0. 86.
