Abstract
The zirconium-mediated synthesis of a new class of air-stable spirocyclic germafluorene-germole (SGG) luminogens is reported. These species contain ring-fused germafluorene and germole units that display color-tunable fluorescence when peripheral aryl substituents are appended. Three distinct pathways are introduced for SGG modification (Stille, Suzuki-Miyaura, and zirconocene-mediated couplings), which enable the preparation of new libraries of molecular and polymeric SGG light-emitters with tunable luminescence and desirable thermal- and photo-stability.
