| 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. |
