The role of Zundel-like ions in the supramolecular self-organization of porphyrin assemblies

Microcrystals engineering using assemblies of di-protonated meso-tetraphenylporphine dimers under Zundel cations operation

“…1 shows it for aqueous THF-HCl with the different concentrations of porphyrin and acid. Usually, such TPP solutions have a strong opalescence that arises immediately after the solutions mixing indicating for the fast protonated dimers self-assembling into nanoparticles and the associates that occurs under Zundel cations action [28]. The self-assembling process is impossible to observe because of the high constant of the dimerization of protonated TPP (1.9 Â 10 9 mol À1 L) [21] that occurs due to hydrophobic affinity of TPP and the hydrogen bonding via water molecules in the dimers.…”

“…In this case all excess ions are perhaps removed from the porphyrin macrocycle because of the hydrogen bonding via water molecules between two TPP units. The water coating around protonated TPP dimers in assemblies is formed due to Zundel cation operation [18,28] that provides the stronger interactions relatively those in water, while the fast proton migration through the water-porphyrin matrix produces more stable clusters. The striking effects in the absorption spectroscopy of di-protonated TPP dimers motivated the study of the detailed structural features of the assemblies up to the final crystallization.…”

New Insight into Electronic Neutrino Creation under X-Ray Absorption by Water Tetrahedron Intercalated with Hydronium Ion (H3O+)

“…Tetrahedral water molecule coordination is the consequence of the orbits orientation in water molecule defined by 2p 4 configuration. Thus, the parameters of polaronic exciton radii in the case of electric field generated by X-ray radiation will be r B , vibration amplitude a x , and the radius of hole polaron r B /2 [15,26]. The most probable wave pathway in the case of polaronic exciton generation is the following, r 1 →r 2 →r 1 →r 4 (r 1 = r B , r 2 = a x , r 4 = r B /2).…”

“…With [29] arisen from water molecules connecting the neighboring porphyrin units (TPPH + and TPP) in the dimer [26]. In the case of spin-orbit interaction with β q = 3.741657387 depending on the quaternary H 2 O coordination instead of β, Eq.…”

“…The latter doublet has been assigned to proton sharing in Zundel cation located between the neighboring porphyrin macrocycles of the dimers [26].…”
