Summary
Metal-organic frameworks (MOFs) exhibit extended electronic and nanosecond spin coherence at low temperatures, outperforming organic linkers. This highlights MOFs
Area of Science:
- Materials Science
- Quantum Information Science
- Photonic Applications
Background:
- Metal-organic frameworks (MOFs) offer tunable structures for quantum information and photonics.
- MOFs can host molecular qubits supporting coherent light-matter interactions.
Purpose of the Study:
- Investigate ultrafast coherent dynamics in a perylene-based MOF (UMCM-313) and its organic linker.
- Determine the influence of MOF structure on electronic and spin coherence.
- Assess MOFs as platforms for quantum photonic and spintronic technologies.
Main Methods:
- Time-resolved two-photon near-field scanning optical microscopy (NSOM) to track electronic quantum coherence.
- Time-resolved and pulsed electron paramagnetic resonance (TREPR and pulse-EPR) spectroscopy to probe spin coherence.
Main Results:
- UMCM-313 exhibits electronic coherence persisting up to picoseconds at 173 K, significantly longer than organic linkers.
- Enhanced coherence in UMCM-313 is linked to periodic chromophore separation and reduced homogeneous broadening.
- Nanosecond spin coherence (237 ± 5 ns at 173 K) was observed in photoexcited triplet states within the MOF.
Conclusions:
- UMCM-313 supports extended excitonic and long-lived spin coherence due to its periodic framework connectivity.
- The coexistence of electronic and spin coherence in MOFs demonstrates their potential for hybrid quantum technologies.
- MOFs can maintain phase-stable quantum states under operationally relevant conditions.

Crystal Field Theory
To explain the observed behavior of transition metal complexes (such as colors), a model involving electrostatic interactions between the electrons from the ligands and the electrons in the unhybridized d orbitals of the central metal atom has been developed. This electrostatic model is crystal field theory (CFT). It helps to understand, interpret, and predict the colors, magnetic behavior, and some structures of coordination compounds of transition metals.

The hemoglobin in the blood, the chlorophyll in green plants, vitamin B-12, and the catalyst used in the manufacture of polyethylene all contain coordination compounds. Ions of the metals, especially the transition metals, are likely to form complexes.
In these complexes, transition metals form coordinate covalent bonds, a kind of Lewis acid-base interaction in which both of the electrons in the bond are contributed by a donor (Lewis base) to an electron acceptor (Lewis acid). The Lewis acid in...

Coordination compounds and complexes exhibit different colors, geometries, and magnetic behavior, depending on the metal atom/ion and ligands from which they are composed. In an attempt to explain the bonding and structure of coordination complexes, Linus Pauling proposed the valence bond theory, or VBT, using the concepts of hybridization and the overlapping of the atomic orbitals. According to VBT, the central metal atom or ion (Lewis acid) hybridizes to provide empty orbitals of suitable...

Network covalent solids contain a three-dimensional network of covalently bonded atoms as found in the crystal structures of nonmetals like diamond, graphite, silicon, and some covalent compounds, such as silicon dioxide (sand) and silicon carbide (carborundum, the abrasive on sandpaper). Many minerals have networks of covalent bonds.
To break or to melt a covalent network solid, covalent bonds must be broken. Because covalent bonds are relatively strong, covalent network solids are typically...

Shortly after de Broglie published his ideas that the electron in a hydrogen atom could be better thought of as being a circular standing wave instead of a particle moving in quantized circular orbits, Erwin Schrödinger extended de Broglie’s work by deriving what is now known as the Schrödinger equation. When Schrödinger applied his equation to hydrogen-like atoms, he was able to reproduce Bohr’s expression for the energy and, thus, the Rydberg formula governing hydrogen spectra.
