Orbital Phase Perspective of Goodenough-Kanamori-Anderson Rules (GKA Rules) in Superexchange Interaction

Goodenough-Kanamori-Anderson rules (GKA rules) in superexchange interaction discriminate the magnetic properties of two magnetic metal ions bridged with an anion. We propose here that the GKA rules can be explained in terms of the orbital phase continuity-discontinuity property of cyclic orbital interaction including direct metal-metal orbital interaction.

A unique tetranuclear Ag(i) complex emitting efficient thermally activated delayed fluorescence with a remarkably short decay time

A novel emissive tetranuclear Ag(i) complex with highly efficient thermally activated delayed fluorescence (TADF) was successfully prepared and characterized. The significant participation of a metal orbital in the occupied frontier orbitals leads to dominant MLCT emission.

Strongest π–metal orbital coupling in a porphyrin/gold cluster system

π–Metal coupling in a porphyrin/gold cluster system at the closest distance was investigated spectroscopically; this system formed an exciplex in the excited state.

Torque control by metal-orbital interactions

The silyl substituent of 3-silylcyclobutene prefers inward rotation rather than outward rotation during a thermal ring-opening reaction, giving the Z-isomer predominantly. This intriguing behavior was explained by assuming electron-accepting interactions between the low-lying σ*-orbital of the silicon-carbon linkage and the highest occupied molecular orbital (HOMO) of the opening cyclobutene system, which are possible only in the inward transition state. On the basis of this finding, a novel method for the stereoselective synthesis of functionalized 1,3-butadiene derivatives from cyclobutenones was developed. Boryl substituents exhibit even stronger preference for inward rotation than silyl substituents as a result of electron delocalization from the cyclobutene HOMO into the vacant p-orbital of boron at the inward transition state.
