Fluorescent Polyethers Incorporating Perylene Diimide Derivatives: Investigating a Strategy of Limiting Aggregation

Macromolecular Materials and Engineering, EarlyView.
This work focuses on the use of perylene diimide (PDI) in the main polymeric chain of poly(arylene ether)s. It attempts to unlock the emission of PDI by randomly distributing it along the main chain to avoid quenching. This is a strategy that can be incorporated toward developing materials for the active layer of Polymeric Light Emitting Diodes (PLEDs).

Dichloridobis[4,4,5,5-tetramethyl-2-(5-methyl-1H-imidazol-4-yl-κN3)-2-imidazoline-1-oxyl 3-oxide-κO]copper(II)

Acta Crystallographica Section E, 2011
In the title complex, [CuCl2(C11H17N4O2)2], the CuII ion, lying on an inversion center, is six-coordinated in a distorted octahedral [Cu(N2O2Cl2)] environment by two N,O-bidentate nitronyl nitroxide radical ligands and two trans-chloride anions.

Robust β‐myrcene block copolymer elastomeric vitrimers

Polymer International, EarlyView.
Myrcene‐based vitrimeric elastomers were compared: statistical (poly(styrene‐stat‐myrcene‐stat‐AAEMA)] versus ‘hard–soft’ diblock (poly(styrene)‐block‐poly(myrcene‐co‐AAEMA)). The diblock's ability to anchor the glassy poly(styrene) blocks in a self‐assembled microstructure was effective – leading to four times higher tensile stress and ten times ...

Localization of dexamethasone within dendritic core-multishell (CMS) nanoparticles and skin penetration properties studied by multi-frequency electron paramagnetic resonance (EPR) spectroscopy [PDF]

, 2016
The skin and especially the stratum corneum (SC) act as a barrier and protect epidermal cells and thus the whole body against xenobiotica of the external environment. Topical skin treatment requires an efficient drug delivery system (DDS).

Nitroxide‐Mediated Polymerization Synthesis of Geminal Bisphosphonate‐Functionalized (Co)polymers and Their Affinity to Hydroxyapatite Surface

Journal of Polymer Science, EarlyView.
A novel styrenic monomer bearing gem‐bisphosphonate groups is synthesized in a single step. The nitroxide‐mediated (co)polymerization of this monomer proceeds in a well‐controlled manner, yielding bisphosphonate‐functionalized (co)polymers with low dispersity.

Cobalt(II) Terpyridin-4′-yl Nitroxide Complex as an Exchange-Coupled Spin-Crossover Material [PDF]

, 2018
pin-crossover (SCO) was studied in [Co(L)2](CF3SO3)2, where L stands for diamagnetic 2,2′:6′,2′′-terpyridine (tpy) and its paramagnetic derivative, 4′-{4-tert-butyl(N-oxy)aminophenyl}-substituted tpy (tpyphNO).

In Situ Self‐Nanostructuring Enables Fast‐Recharging of an Aqueous‐Processed Organic Small Molecule Cathode

Small, EarlyView.
Self‐nanostructuring of redox‐active organic small molecules through in situ electrochemical postcrosslinking enabled an aqueous‐processed, stable, fast‐rechargeable organic electrode even with a high active content ratio and mass loading. ABSTRACT Redox‐active organic materials (ROMs) for batteries are emerging as sustainable alternatives to inorganic

Molecules with enhanced electronic polarizabilities based on defect-like states in conjugated polymers [PDF]

, 1991
Highly conjugated organic polymers typically have large non-resonant electronic susceptibilities, which give the molecules unusual optical properties. To enhance these properties, defects are introduced into the polymer chain.

Synthesis of Deprenyl-like nitroxide free radicals and their diamagnetic derivatives [PDF]

, 2011
Synthesis of paramagnetically modified deprenyl and oxotremorine is reported. Starting from 5- and 6-membered 2,5-disubstituted nitrones (1, 6) or 4-phenyl-2,5,5-trimethyl-1H-pyrroline 1-oxide (11) deprenyl or oxotremorine like nitroxides were ...
