Synthesis and Luminescence Modulation of Pyrazine-Based Gold(III) Pincer Complexes

The first examples of pyrazine-based gold(III) pincer complexes have been synthesized; their intense photoemissions can be modified by interactions with the non-coordinating pyrazine-N atom. Luminescence modulation is possible without the need for altering the ligand framework. Emissions shift from red (77 K) to blue (298 K) due to thermally activated delayed fluorescence (TADF

On the electronic excited states of sulfur dioxide

We report Ab Initio calculations for the ground and lowest electronic excited states of sulfur dioxide. Molecular geometries, together with the electric dipole moment, dipole polarizability and first hyperpolarizability are given for each state. Ground state properties were calculated using the HF and B3LYP models, whilst excited states were modelled using CIS and CIS(D). Our results reveal substantial differences between these properties
