Self-Assembling Poly(dioxaborole)s as Blue-Emissive Materials
2006-12-27T00:00:00Z (GMT) by
Conjugated, borole-linked polymers have been self-assembled based on boronate ester formation between a fluorene-2,7-diboronic acid and 1,2,4,5-tetrahydroxybenzene. Readily soluble polymers with molecular weights approaching 60 000 have been generated with materials exhibiting extended conjugation over approximately 3−5 borole linkages. Emission from these polymers reaches into the visible (blue) range, representing a novel class of blue-emitting materials.
