Novel Blue Emitting Material with High Color Purity

Abstract

A stable non-polymeric organic glass with a high glass transition temperature has been prepared and its properties are reported here. The purest blue emission so far achieved can be obtained with a non-doped, low molecular weight bis(spirobifluorenyl) anthracene derivative (see Figure). High-quality amorphous films of this compound with high morphological stability could be prepared by vapor deposition.
