PHENANTHRENE CRYSTALS FLUORESCENCE UNDER HIGH-PRESSURE AND SHEAR
The material was received by the Editorial Board: 07.07.2009
Investigations of crystalline phenanthrene in the Bridgman diamond anvils under pressure up to 5,0 GPa and simultaneous shear caused by optical microscopy and fluorescence spectroscopy were carried out. It’s proven that phenanthrene fluorescence spectrums are reversibly changed under high pressure. The phenanthrene vibrational structure of lines disappears similar to the one of the anthracene. Dimerization or any other irreversible changes under combination of high pressure and shear in phenanthrene, unlike anthracene, were not observed. Keywords:
phenanthrene, anthracene, high pressure, shear, mechanochemistry, dimerization, fluorescence.
