Abstract

original image

The solid state emission of di(p-methoxylphenyl) dibenzofulvene and analogues is polymorphism dependent. The crystalline forms are strongly emissive, whereas the amorphous solid is weakly fluorescent. As reported by Guanxin Zhang, Dequing Zhang, and co-workers on page 4862, organic crystalline microrods based on the same molecular entity exhibit strong blue and yellow-green emission, outstanding optical waveguide behavior, and amplified spontaneous emission.
