Anisotropic molecular packing is a key feature that makes glasses prepared by physical vapor deposition (PVD) unique materials, warranting a mechanistic understanding of how a PVD glass attains its structure. To this end, ...

Glasses of a common OLED host material, 4,4′-bis(N-carbazolyl)-1,1′-biphenyl or CBP, were prepared by vapor deposition at various substrate temperatures. Consistent with previous work, the substrate temperature during ...
