Angewandte Chemie, Volume 135, Issue 48, November 27, 2023., 2023 Electron paramagnetic resonance (EPR) shows that a vanadyl‐copper meso‐meso linked bisporphyrin complex has good spin coherence and a sizeable magnetic exchange interaction, making it suitable for operating two‐qubit molecular spin‐based quantum gates over a wide range of operation conditions.

Chirality‐Induced Spin Selectivity: An Enabling Technology for Quantum Applications
Advanced Materials, Volume 35, Issue 28, July 13, 2023., 2023 Molecular spins are promising qudits but their weak interaction with external fields makes single‐molecule readout challenging. A solution that exploits chirality‐induced spin selectivity (CISS) in photoinduced electron transfer is envisioned in this work.

Liquid-Liquid Microextraction of Vanadyl Porphyrins by Nano-baskets [PDF]
, 2012 The novelties of this approach are introducing the self-settled dispersive liquid-liquid microextraction technique to remove the centrifuging step, conducting the dispersive liquid phase microextraction in complex organic systems, applicability of water as disperser phase, and nano-extraction of charged porphyrins by nano-baskets of calixcrown, which ...

, 2021 Nickel and vanadyl porphyrins belong to the so-called fossil geo- or sedimentary porphyrins. They occur in different types of organic matter-rich sediments but mostly occur in crude oils and their source rocks, oil shales, coals, and oil sands.
