Synthesis of New Bioinorganic Systems Based on Nitrilium Derivatives of closo-Decaborate Anion and meso-Arylporphyrins with Pendant Amino Groups

In this work we elaborated an approach to the synthesis of meso-arylporphyrin with pendant amino groups.This approach is based on the preliminary functionalization of 4-(4-bromobutyloxy)benzaldehyde by potassium phthalimide, its condensation with pyrrole and removing the protecting phthalimide group.New boron-porphyrin conjugates were synthesized based on final aminoporphyrin and closo-decaborate anion [B 10 H 10 ] 2-.New conjugates were obtained using microwave synthesis which reduced reaction time in 2 fold.Spectral properties of the conjugates were evaluated based on electron absorption spectra and steady-state fluorescence.
