Fine-Tuning of Boron Complexes with Cage-Shaped Ligand Geometry: Rational Design of Triphenolic Ligand as a Template for Structure Control

Boron complexes surrounded with organic cages were controlled precisely by a remote atom placed at the bottom of the cage. A replacement
of the bottom tether atom (carbon or silicon) changed the characteristics (kinetic and thermodynamic factors) of boron complexes by geometric
effects. A theoretical study shows that the bottom atoms also control eigenvalues of MO. This cage complex will provide a systematic template
for fine-tuning of metal complexes to create various properties.
