Synthesis of tetraferrocenylporphyrin and new metal complexes: Searching for reliable synthetic procedures

Abstract

The tetraferrocenylporphyrin synthetic procedure was performed varying different reaction conditions. Mg, Mn, Pd and Cd complexes were synthesized and preliminarily studied. The results obtained show that the synthetic procedure strongly depends on catalyst, solvent and reagents concentration, even more than what observed with similar tetraarylporphyrins; concentration of substrates plays an important role in determining the outcome of the reactions

“…ZnTPP was purchased from Aldrich and used as received. H 2 TFcP, [3] ZnTFcP, [4] PdTFcP, [5] and FcInTFcP [6] complexes were prepared as described previously by us or other authors.…”

“…Ferrocene-containing porphyrins [1][2][3][4][5][6][7][8][9][10][11][12][13][14] and their analogs such as BODIPYs, [15][16] aza-BODIPYs, [17] BOPHYs, [18] and MB-DIPYs [19] in which ferrocene fragment is fully conjugated with the chromophore core were intensively studied because of their prominent mixed-valence and electron-migration properties. These robust platforms were thought for application in molecular electronics, light-harvesting, photo-and electrocatalysis, quantum cellular automata, and redox-switchable fluorescent devices.…”

“…These robust platforms were thought for application in molecular electronics, light-harvesting, photo-and electrocatalysis, quantum cellular automata, and redox-switchable fluorescent devices. [20] Although the fundamental properties of the simplest members of this family of compounds (i. e., 5,10,15, Figure 1) [1][2][3][4][5][6][7][8][9]20] are now well understood, the knowledge about their excited states nature is still underexplored. Indeed, it is well-known that the fluorescence in the metal-free and transition-metal TFcPs is quenched.…”

“…It is expected that the photophysics of the MTFcP complexes will be different from that in regular porphyrins. [23] In particular, MTFcP complexes are non-fluorescent, [2][3][4][5][6][7][8] while the regular porphyrins are known for their fluorescence and phosphorescence, which is reflective of their different electron-transfer properties and excited states lifetime.…”

“…Furthermore, linking our experience in synthesis optimization [24][25][26][27][28][29][30][31] together with a broad investigation of literature data, we have also optimized a one-pot reaction, aimed to overcome the aforementioned synthetic troubles, thus improving the application of this class of compounds as dyes in the solar cells field, in the photodynamic therapy, likewise to study their interactions with DNA and proteins. [32] the π-stacked dimer of MB (Figure 1) converged to a minimum of energy, whereas the dimeric form of 1 did not.…”
