Abstract:

The molecular packing structure in a thin film of the liquid crystalline phthalocyanine, 1,4,8,11,15,18,22,25-octahexylphthalocyanine (C6PcH2), which is a promising small-molecular material for solution-processable organic thin-film solar cells, has been investigated by X-ray diffraction (XRD) measurement. The crystal structure of C6PcH2 in the spin-coated film was determined to be a centered rectangular structure (a= 36.4Å, b 20.3 Å). The tilt angle of the phthalocyanine core normal vector was 34–39° from the column axis, and the shortest intermolecular distance was 3.9–4.0 Å. The crystal str

Abstract:

Thermal reaction of phthalonitrile with hafnium powder under iodine monobromide (IBr) yields a new type molecule: bis(hafnium(IV) stapled phthalocyanine) derivative complex. X-ray single crystal analysis shows that the complex molecule consists of two hafnium phthalocyanine units bridged by the unique internal ligand that stapled by two carbon–carbon [Formula: see text] bonds to both HfPc-units. The internal dianionic ligand consists of two fragments, each of them present the three fourth part of phthalocyaninate ring.

In 1970, Breedlove and Trammel predicted that, because of radiation damage, the direct imaging of individual organic molecules by electron or X-ray microscopy was not possible.

To minimize damage, we have therefore constructed a transmission electron microscope with nanometer resolution, which operates at 7 - 300 eV, below the threshold for most inelastic processes.

Abstract:

The crystal structure of a polymorph of copper phthalocyanine (CuPc) grown on a KCl substrate is redetermined by transmission electron diffraction. It has a triclinic unit cell containing one molecule; the crystal does not have a herringbone-type molecular arrangement, which is a common packing mode of planar phthalocyanines. The molecular packing is determined by the diffraction intensity with the aid of the calculation of molecular packing energy. One of the striking features of this polymorph is its stacking mode within a molecular column: the molecular stacking direction projected on a mol

XPS analysis of MoO2powder reveals presence of +5 and +6 oxidation states in Mo 3d core level along with +4 state. The residue of MoO2powder indicates substantial reduction in higher oxidation states while keeping

The compound shows an increased solubility compared to its SiPcCl 2 precursor and this allowed solution 1 H NMR characterization. The assignment of the 1 H NMR signals for the axial ligands is greatly facilitated due to the anisotropic high ring current effects from the macrocycle. In addition, good quality crystals were grown from this more soluble material for molecular structure determination by single-crystal X-ray diffraction analysis.
