The fluorescence spectra of tetra-aza macrocycles containing pyridine rings and their lithium complexes were measured and specific fluorescence behaviors were found. That is, the complexation of tetra-aza macrocycle with lithium ion dramatically enhances the fluorescence intensity (over 1100 fold).

the macrocyclic ring is capable of catalyzing efficient oxidation of various alkanes and aromatic compounds with hydrogen peroxide. Catalyzed by this complex 4, a variety of alkenes can be oxidized by hydrogen peroxide and their epoxides are formed in high yields. In contrast, complex 2 shows the failure to catalyze efficient oxidation of hydrocarbons with hydrogen peroxide. To evaluate the catalytic
