Two‐ and Three‐Spin Hybrid Inorganic‐Organic [2]Rotaxanes Containing Metallated Salen Groups
Chemistry – An Asian Journal, Volume 19, Issue 20, October 16, 2024.Heterometallic paramagnetic rotaxanes substituted with additional spins are reported. These additional spins are coordinated to salen ligands and the structure is confirmed in solution by pulsed EPR spectroscopy‐ Abstract Mono‐ and bis‐salen functionalised [2]rotaxanes have been synthesised from the esterification of [2]rotaxanes containing phenol ...

Bulletin of the Korean Chemical Society, Volume 45, Issue 10, Page 835-862, October 2024.This review discusses electron paramagnetic resonance (EPR) spectroscopic methods for characterization of transition metal complexes. EPR spectroscopy provides valuable insights into the geometric, electronic, and magnetic properties of paramagnetic molecules, reinforcing the blind spot of nuclear magnetic resonance spectroscopy‐based structural ...

Metalloporphyrins as Building Blocks for Quantum Information Science
Advanced Optical Materials, Volume 12, Issue 18, June 26, 2024.Porphyrins represent ideal building blocks for quantum information science. Their ability to accommodate metal ions makes them an excellent platform for quantum bits. Their distinctive molecular structure enables the formation of quantum logic gates and higher‐dimensional systems.

Electronic and Magnetic Properties of a Monolayer of VOTPP Molecules Sublimated on Ag(100)
Advanced Physics Research, Volume 3, Issue 5, May 2024.Vanadyl tetraphenyl porphyrin molecules (VOTPP) exhibit weak interaction with the Ag(100) surface, displaying only subtle screening effects in the monolayer. The preservation of electronic and spin properties holds promise for quantum applications.
