The Overlooked Dual Phosphorescence of Lappert's Diamino Stannylene Sn[N(SiMe<sub>3</sub>)<sub>2</sub>]<sub>2</sub>.
Ontology highlight
ABSTRACT: The first stable heavy carbene homologues, the heavy tetrylenes, were reported in 1973 by Lappert and coworkers. These tetrylenes were extensively investigated with respect to ground state reactivity, such as small molecule activation, insertion into σ-bonds, coordination chemistry, materials chemistry, or catalysis. Their photophysical properties remained essentially unexplored. We report that the bright yellow-colored diamino stannylene Sn[N(SiMe3)2]2 shows thermally activated dual orange/green phosphorescence with microsecond lifetime in fluid solution at room temperature, which has been overlooked for more than 50 years. These unique electronic and photophysical properties are studied in detail by temperature-dependent time-resolved emission and absorpt
