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 [B10H10](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.
