Heteroleptic Cr 4+ molecular color center candidates

Year: 2026

Type: article

Abstract: diamagnetic host (4') even displays optically resolvable spin sublevels under zero applied magnetic field; using variable-field PL spectroscopy, we optically determine its ZFS parameters. These results will lead toward the realization of well-defined spin-analyte interactions and subsequent spatial control of molecular color centers, wherein tunability is maintained through the donor at the axial coordination site.
