Chemistry is traditionally divided into organic and inorganic chemistry. HPLC of Formula: C34H28Cl2FeP2Pd, The former is the study of compounds containing at least one carbon-hydrogen bonds.In a patent，Which mentioned a new discovery about 72287-26-4
Synthesis, crystal structure, and conjugation properties of phenanthroline copper phosphine complexes
Facial synthetic method of 4,7-position conjugation extended phenanthrolines and X-ray structure of copper phosphine phenanthroline complexe were reported. The crystal structures showed pi-stacking and hydrogen bonding, and a small torsional angle between phen and phenylacetylene. These complexes exhibited strong conjugation dependant MLCT luminescence. The electronic and fluorescence spectra displayed a gradual red shift of the MLCT band as the conjugation increased. The presence of the phenyl groups reduced the energy of the pi? state in the d-pi? MLCT transition, allowing for the red shift. The electron-donating tri-isopropylsilyl (TIPS) groups on the ethynyl moiety increased the energy of the MLCT charge vector, allowing for the blue shift at the luminescence.
