An efficient synthesis of versatile terpyridine analogues for cyclometallated luminescent cyclodextrins
摘要:
An efficient synthetic method for preparing functionalised terpyridyl analogues based on Negishi's zinc coupling is developed. These ligands form cyclometallated complexes; attaching them to cyclodextrins allows preparation of luminescent cyclometallated ruthenium cyclodextrins for the assembly of photoactive units via non-covalent interactions, (C) 1999 Elsevier Science Ltd.

Described herein are transition metal complexes containing nickel(II), as the central metal atom, and tridentate and tetradentate ligands. The transition metal complexes also include an ancillary ligand with strong σ-donating properties. The ancillary ligand enhances the luminescence by increasing the chances of populating the emissive state. The transition metal complexes are emissive at room temperature and/or low temperature in various media, rendering them useful as light-emitting materials for OLEDs.
