WebDec 1, 2013 · Phenylacetylide ligand mediated tuning of visible-light absorption, room temperature phosphorescence lifetime and triplet–triplet annihilation based up-conversion of a diimine Pt (II) bisacetylide complex - ScienceDirect Dyes and Pigments Volume 99, Issue 3, December 2013, Pages 908-915 WebThe emission lifetime of the 4‘-pyrenyl-2,2‘:6‘,2‘ ‘-terpyridyl phenylacetylide complex ( 8) is longer than 2 μs at room temperature, and more than 300 μs at 77 K, while the other three complexes possess an emission lifetime of 200−400 ns at room temperature and tens of microseconds at 77 K. Replacing the chloride ligand in the 4‘-naphthyl, …
WebDec 3, 2024 · Complexes of redox-active ferrocene based bulky bisphosphane ligands with Cu (I) phenylacetylide have been prepared. Owing to their limited solubility, the complexes have been characterized by solid state NMR and complementary further methods featuring luminescence at room temperature. Abstract WebOn the other hand, incorporation of both NHC and phenylacetylide ligands could suppress the non-radiative decay process. This indicates that the electron distribution in the excited state is localized not on the NHC ligand, but on the phenylacetylide ligand. Therefore, complexes containing phenylacetylide ligands exhibited higher Φ. Of ...
