Abstract

The existence of a second polymorphic form of the hole transport material N,N-diphenyl-N,N-bis(3,3-methylphenyl)-[(1,1-biphenyl)]-4,4-diamine has been confirmed using both Pawley and Rietveld refinement of structural information against high-resolution synchrotron X-ray powder diffraction data.
