Changing N^C^O to C^N^O Coordination in Cyclometalated Pt(II) and Pd(II) Complexes Modulates Stability and Emission Characteristics: Toward Brighter Versatility

Chemistry – A European Journal, EarlyView.
A new class of cyclometalated metal complexes with pincer luminophores (C^N^O and N^C^O) is reported. They unite high photoluminescence efficiencies in liquid solutions at r.t. with tunable colors across the visible spectrum and convenient synthetic accessibility.

Bioinspired Design and Synthesis of Polyphenolic Star‐Like and Hyperbranched Polyester Models

Chemistry – A European Journal, EarlyView.
Gallotannin‐inspired star‐like and hyperbranched aromatic polyesters were synthesized from D‐glucose and ABn‐type phenolic acid monomers, such as protocatechuic acid. This bioinspired approach afforded polyphenolic polymeric nanoparticles able to encapsulate hydrophobic dyes, opening new perspectives for biobased encapsulation and delivery systems ...

Redox‐Targeting Reactions of Viologen‐Based Shuttles and Polymers Translated From Nonaqueous to Aqueous Electrolyte

Chemistry – A European Journal, EarlyView.
. ABSTRACT Redox‐targeting flow batteries (RTFBs) present an attractive strategy for enhancing the energy density of conventional redox flow batteries (RFBs) by integrating heterogeneous energy storage materials as capacity boosters. However, nearly all RTFB systems have been developed with nonaqueous redox chemistries, while capacity boosters in ...

VOCs Adsorption and Exchange Properties in Bispidine‐Based Mn(II) 1D CPs Made of Orthogonally Oriented Linear Chains

Chemistry – A European Journal, EarlyView.
Combining the chiral bispidine ligand L1 with MnCl2 affords coordination polymers (CPs) with an unusual topology for this family of compounds, consisting of orthogonally packed ribbon‐like one‐dimensional (1D) chains. Their behavior was investigated through single‐crystal‐to‐single‐crystal exchange with aromatic volatile organic compounds (VOCs) and ...

Revisiting the synthesis of dimethyl carbonate from methanol and carbon dioxide

The Canadian Journal of Chemical Engineering, EarlyView.
Abstract The process for producing dimethyl carbonate (DMC) from carbon dioxide (CO2) and methanol is explored in this article. It provides an overview of the thermodynamics involved in DMC synthesis, discussing the challenges and potential solutions. The article highlights the reported use of catalysts and dehydrating agents to improve DMC yield and ...

Selective Modification of the Product Profile of Biocatalytic Hydrolyzed PET via Product‐Specific Medium Engineering

ChemSusChem, Volume 18, Issue 6, March 15, 2025.
The product profile of enzymatically hydrolyzed PET can be modified by medium engineering and thereby adapted to a desired product. TPA, MHET or BHET can be forced as the predominant product using a basic pH (blue), 25 % ethylene glycol (EG) and IsPETasewt (green) or ≥25 % EG and LCCICCG (pink), respectively.

Triterpene benzoates from the bark of Picramnia teapensis (Simaroubaceae)

Journal of the Brazilian Chemical Society, 2001
Two new benzoic acid esters of triterpene alcohols [lup-20(29)-en-28-oic acid 3alpha,7beta-dibenzoate and 3alpha-hydroxy-lup-20(29)-en-28-oic acid 7beta-benzoate] were isolated from the stem bark of Picramnia teapensis Tul.

Visible light photoredox-catalyzed deoxygenation of alcohols

Beilstein Journal of Organic Chemistry, 2014
Carbon–oxygen single bonds are ubiquitous in natural products whereas efficient methods for their reductive defunctionalization are rare. In this work an environmentally benign protocol for the activation of carbon–oxygen single bonds of alcohols towards
