Synthesis of the Axially Substituted Titanium Pc-C₆₀ Dyad with a Convenient Method

Abstract

[structure: see text] We successfully synthesized the axially substituted titanium Pc-C(60) dyad with a convenient method that improves on the traditional asymmetrical phthalocyanine routine to covalently linked phthalocyanines with other functional molecules. The intramolecular photoinduced process between phthalocyanine donor and fullerene acceptor was preliminarily studied.

Synthesis and strong optical limiting response of graphite oxide covalently functionalized with gallium phthalocyanine

“…The exploitation of the chemical reactivity of the Ga-Cl bond in the R x PcGaCl (R: peripheral substituents in the Pc macrocycle) can allow the preparation of a series of highly soluble axially substituted and bridged Pc complexes [7][8][9][10][11][12][13][14]. Axial substituents in Pcs influence favorably nonlinear optical (NLO) absorption for the presence of a dipole moment perpendicular to the macrocycle in the axially substituted phthalocyanines [15][16][17][18][19][20][21]. Substitution and dimerization of the Pc monomer resulted in significant reductions in the saturation energy density of the material, displaying clear evidence of the usefulness of structurally modifying the phthalocyanine unit.…”

Permeability, Purity, and Yield in Crystal Beds

“…The HOMO/LUMO values of the samples were experimentally calculated from the onset of the redox potentials by taking the known reference level for ferrocene, 4.8 eV below the vacuum level, according to the equation of HOMO/LUMO=−[ E ox/red − E ox. (ferrocene) ]−4.8 15. In our electrochemical experiments, ferrocene exhibited an onset oxidation potential of 0.38 V versus Ag/AgCl.…”

One-pot Synthesis of Soluble Nanoscale CIGS Photoactive Functional Materials

“…Upon heating at 100 °C for several minutes, the solid crystalline phase of this complex is transformed into a viscous birefringent liquid. Basically, the HOMO/LUMO values of materials can be experimentally estimated by the onset of the redox potentials [9] taking the known reference level for ferrocene, 4.8 eV below the vacuum level, according to the following equation: HOMO/LUMO = − E onset − E ox. (ferrocene) −4.8 eV.…”
