Raman and Infrared Spectra of Cd(15NH3)2Cl2 and Local Symmetry Force Field

The infrared and Raman spectra of Cd(¹⁵NH₃)₂Cl₂ are reported and a comparison is made between the normal and ²H isotope substituted compounds. A further refinement of the Local Symmetry Force Constants was carried out.     

Metal-nanoparticle-induced crystallization of amorphous Ge film using ferritin

The metal-induced lateral crystallization (MILC) of an amorphous Ge (a-Ge) thin film using Ni nanoparticles (NPs) was investigated. Ni-NPs were formed and evenly distributed onto a 30 nm thick a-Ge film by cage-shaped protein. After complete elimination of protein shell, crystal growth was performed at 400 °C. Raman spectra and electron backscatter diffraction (EBSD) studies revealed that a poly-Ge film with a maximum grain size approximately 1 μm was successfully formed. The Ni contamination in the poly-Ge film was reduced by more than one order of magnitude compared with that in the case of a conventional MILC process.     

Synthesis and Characterization of 6,13‐Diamino‐Substituted Pentacenes

A series of 6,13‐diamino‐substituted pentacenes 1 a – d has been prepared and characterized as a new class of pentacene derivatives with strong donor ability and enhanced solubility in common organic solvents. The spectroelectrochemical and DFT studies revealed that the two‐electron oxidation process was accompanied by the substantial structural change into a butterfly‐like conformation of the pentacene moiety. More importantly, the extent of deformation from the planar pentacene moiety in the dications of 6,13‐diaminopentacene is tunable by varying the N‐substituents.
