Intraligand fluorescence and phosphorescence of tris(pyrazolyl) hydridoborate complexes

Zusammenfassung

The complexes GdTP3 and PPh(3)AgTp with Tp = Hydridotris(I-pyrazolyl) borate in the solid state are characterized by rather similar luminescence spectra which consist of a fluorescence near 390 nm and a phosphorescence near 480 nm. These emissions originate from a Tp(-) pi pi * IL singlet and triplet, respectively. Owing to the heavy-atom effect of Gd and Ag the phosphorescence appears also at rt. (C) 2008 Elsevier B.V.
