A Polymorph Lost and Found: The High‐Temperature Crystal Structure of Pentacene
Source abstract
Abstract
A well-defined structural phase transformation is observed in bulk single crystals of pentacene, whereas pentacene powders heated above the phase-transformation temperature do not always fully convert, and upon cooling, coexistence of the two polymorphs is observed down to room temperature. The first-order phase transformation is isostructural: the close-packed herringbone-type layers shift against each other, keeping the same symmetry.
