Excited State Lifetimes

Nuclear excited state lifetimes have been determined by direct timing, using a pulsed beam and a Ge(Li) detector in singles. Results are 35Cl (3163 keV), 46 ± 6 ps; 37Cl (3103 keV), 16 ± 9 ps; 39K (2813 keV), 71 ± 5 ps; 39K (3598 keV), 91 ± 27 ps. M2 and E3 transition strengths of the transitions in 35Cl and 37Cl are compared with previous theoretical calculations.

Absorption and fluorescence properties, excited state lifetimes and fluorescence quantum yields were determined for a series of 3,5-diarylaminobenzene derivatives in solvents of different polarities. The role of the nitrile, methyl, phenyl and naphthyl substituents is discussed. Especially the steric effects on the spectroscopic behaviour of the investigated molecules are studied.

New luminescent “carbene-metal-amide” (CMA) Cu, Ag and Au complexes based on monocyclic (C6) or bicyclic six-ring (BIC6) cyclic (alkyl)(amino)carbene ligands illustrates the effects of LUMO energy stabilization, conformational flexibility and excited state energy on the photoemission properties, leading to near-quantitative quantum yields, short excited state lifetimes Cu > Au > Ag down to 0.5 µs and high radiative rates of 10<sup>6</sup> s<sup>–1</sup>.
