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.
