Reactions of HNO with Metal Porphyrins: Underscoring the Biological Relevance of HNO [PDF]
, 2014 Azanone (1 HNO, nitroxyl) shows interesting yet poorly understood chemical and biological effects. HNO has some overlapping properties with nitric oxide (NO), sharing its biological reactivity toward heme proteins, thiols, and oxygen.

Advanced Materials, EarlyView.This review explores how in situ and operando spectroscopic techniques reveal the real‐time behavior of reticular materials, including MOFs and COFs. These methods track material formation and functionalization, structural changes, defect formation, dynamic responses to external triggers, and catalytic processes.

Advanced Materials, EarlyView.Hierarchically porous covalent organic frameworks (hCOFs) are constructed using a solvothermal template‐induced synthetic strategy. Commercially available zinc oxide nanoparticles are employed as hard template enabling an increase in total pore volume in a series of COFs.

Electrically addressing the spin of a magnetic porphyrin through covalently connected graphene electrodes [PDF]
, 2019 We report on the fabrication and transport characterization of atomically-precise single molecule devices consisting of a magnetic porphyrin covalently wired by graphene nanoribbon electrodes. The tip of a scanning tunneling microscope was utilized to contact the end of a GNR-porphyrin-GNR hybrid system and create a molecular bridge between tip and ...

When do tripdoublet states fluoresce? A theoretical study of copper(II) porphyrin [PDF]
arXiv, 2023 Open-shell molecules rarely fluoresce, due to their typically faster non-radiative relaxation rates compared to closed-shell ones. Even rarer is the fluorescence from states that have two more unpaired electrons than the open-shell ground state, for example tripdoublet states (a triplet excitation antiferromagnetically coupled to a doublet state).

Responsive Molecules for Organic Neuromorphic Devices: Harnessing Memory Diversification
Advanced Materials, EarlyView.Responsive molecules are essential for organic in‐sensor computing devices. This Review highlights recent advances in thedesign, synthesis, and incorporation of electrically, optically, and magnetically responsive molecules in multifunctional synaptic perception devices endowedwith both nonvolatile and volatile memory diversification. By exploiting the

Altering the Coordination of Iron Porphyrins by Ionic Liquid Nanodomains in Mixed Solvent Systems [PDF]
, 2017 The solvent environment around iron porphyrin complexes was examined using mixed molecular/RTIL (room temperature ionic liquid) solutions. The formation of nanodomains in these solutions provides different solvation environments for substrates that could
