Extended triphenylamine conjugated systems derivatized by perfluorophenyl groups
摘要:
Two triphenylamine derivatives bearing terminal perfluorophenyl groups have been synthesized. Their HOMO. LUMO levels and electronic band gap have been evaluated by spectroscopic and electrochemical measurements and rationalized with theoretical calculations. X-ray structure analysis of crystals allowed the observation of multiple intermolecular interactions due to the presence of the perfluorophenyl pendant groups. The multiplication of these interactions explains the differences between calculated (in gas phase) and observed (in solid states) structures. (C) 2011 Elsevier Ltd. All rights reserved.
