Spin crossover and valence tautomerism conductors
Abstract Multifunctional molecular materials exhibiting both magnetic bistability and electrical conductivity have excellent application potential in microelectronic devices. In the last two decades,
Design of organoruthenium complexes for nanoparticle functionalization
Abstract In recent years, extensive research efforts have been focused on loading metal complexes onto macromolecular systems such as nanoparticles. We report a ligand with a catechol group based on
Expanding the DOPA Universe with Genetically Encoded, Mussel‐Inspired Bioadhesives for Material Sciences and Medicine
TLDR
OTSs based on genetic code engineering in reprogrammed microbial strains new and promising tools in bioinspired materials science should enable spatiotemporal control over the complex adhesion process, because the catechol function can be masked by suitable chemical protection.
Impact of Group 10 Metals on the Solvent-Induced Disproportionation of o-Semiquinonato Complexes.
TLDR
The present work demonstrates that solvent polarity and the dipole moments of the SQ complexes promote disproportionation, which can be controlled by a judicious choice of the metal ion, solvent, and temperature.
Effects of electric field on a copper–dioxolene complex adsorbed on a gold surface
Abstract A model of a copper–dioxolene complex linked to Au(1 1 1) surface with butanethiol linker is investigated using first-principles methods. It is shown that the complex adsorbed at the surface
Highly polar solvent-induced disproportionation of a cationic Pt(II)-diimine complex containing an o-semiquinonato.
TLDR
The present study demonstrates that cationic [1](+) is subject to an unprecedented solvent-induced disproportionation in highly polar solvents such as DMSO and DMF, which results in the formation of 1 and a free benzoquinone.
Adsorption of a metalorganic complex at a metal surface: A density functional theory study vs. model description
A modification of the electronic and magnetic structure of a metalorganic complex by chemisorption at a metallic surface is addressed. The density functional theory (DFT) is applied to investigate a
Exploring excited states of Pt(II) diimine catecholates for photoinduced charge separation.
TLDR
Overall, this work demonstrates the use of Pt(diimine)(catecholate) complexes as potential photosensitizers in solar cells, and the first application of photoacoustic calorimetry to Pt(II) complexes in general.
Solution Dynamics of Redox Noninnocent Nitrosoarene Ligands: Mapping the Electronic Criteria for the Formation of Persistent Metal-Coordinated Nitroxide Radicals.
TLDR
The results presented here highlight the inherent instability of metal-coordinated nitroxide radicals and suggest a general synthetic strategy for kinetically stabilizing these species in solution.
