title: Blue fluorescent 4a-Aza-4b-boraphenanthrenes.
abstract: [structure: see text]. Phenanthrene analogues with internalized B-N moieties were found to afford blue light emission with good quantum efficiencies, whereas the isomeric species with peripheral B-N moieties displayed only UV emission behavior, like the all-carbon framework.
