Polymorphism and the influence of crystal structure on the luminescence of the opto-electronic material 4,4′-bis(9-carbazolyl)biphenyl†
Abstract
Three polymorphs of 4,4′-bis(9-carbazolyl)biphenyl were prepared and characterized by X-ray diffraction and luminescence spectroscopy. Electronic structure calculations were performed to examine the influence of the molecular geometry on the HOMO and LUMO energy levels and calculated electronic transitions.
