We report here a complete study of coordination of the 5-aminomethyl- [13]aneN4 with chromophoric groups (anthracene, pyrene and naphtalene) by four metals: Zn(II), Cu(II), Ni(II) and Cr(III). We aim to study the effect of the C-functionalization of the macrocycle on the stability of the metal complexes and the size of the metal impact on the quenching of fluorescence of the chromophoric groups. The results obtained by spectrometry, EPR and X-ray of the metal complexes confirm that the copper is pentacoordinate by four nitrogen atoms of the macrocycle, but the chromium and nickel complexes are hexacoordinated in octahedral geometry. For all metal complexes, the coordination of the nitrogen atom is observed with the primary amine function.
