Reaction yields for the DIPY were relatively good and in the range of 30-90%. N-H protons of the dipyrrin moiety show a broad weak resonance (sometimes not easy to detect) in the range of 11-13 ppm in their 1 H NMR spectra, as their arrangement results in a planar conformation with a fast tautomeric exchange of the N-H proton between the nitrogen atoms of the pyrrolic units. The aromatic properties of these compounds are demonstrated by the 1 H NMR shifts where β-protons appear in the range of 6.3-6.7 ppm and α-protons appear in the range of 7.5-7.7 ppm. Aluminum salt AlCl3 in mild basic conditions was utilized for the N-H deprotonation and complex formation. The absence of α-or βpyrrole substituents resulted in a less sterically hindered environment which, along with the presence of the aluminum trivalent metal ion formed the tris(dipyrrinato) complexes. Attempts for in situ complexation, of the respective dipyrrins without purification, as it is common in the case of BODIPY complexes, were unsuccessful similar to reports for other trivalent Group 13 metal ion complexes. In our case, TLC reaction monitoring showed predominately the dipyrrin spot and by-product formation with a less intense orange spot of the desired AL(DIPY)3 compound. Therefore, dipyrrin purification prior to complexation is essential in order to access the corresponding AL(DIPY)3 complexes in good yields. The majority of the aluminum complexes were obtained in moderate to high yields of 50-90% with the lowest yield being found for the mesityl derivative (13b, 18%).
