Porous Deep Eutectic Solvents-Unfulfilled Dream or the Next Breakthrough in Scientific Innovation?

Porous deep eutectic solvents (PDES) are capturing the imagination of scientists, promising a revolutionary leap in material science. These innovative materials, blending the versatility of deep eutectic solvents (DES) with the intricate architectures of porous structures, offer an exciting array of applications-from green chemistry and catalysis to energy storage and environmental remediation. However, the journey from laboratory curiosity to industrial application is fraught with challenges.

Application of a simple copper(II) complex compound as an epinephrine selective voltammetric sensor in the presence of uric acid under aqueous conditions.

Developing sensors with high sensitivity and selectivity for detecting neurotransmitters under near-physiological conditions is a major challenge and is crucial for preventing diseases of the nervous, cardiovascular, and endocrine systems. Most existing systems that meet these requirements involve either complicated synthesis processes, require sulfur groups, or are not functional under aqueous conditions. Herein, we report that the self-organisation of a simple imine ligand L with copper(II) tetrafluoroborate leads to the formation of a [CuL](BF) complex (CuL) with a 2 : 1 ligand-to-metal ratio, as confirmed by high-resolution electrospray ionization mass spectrometry (HR ESI-MS), Fourier-transform infrared (FT-IR) spectroscopy and single-crystal X-ray analysis.

Better Together: Photoredox/Copper Dual Catalysis in Atom Transfer Radical Polymerization.

Photomediated Atom Transfer Radical Polymerization (photoATRP) is an activator regeneration method, which allows for the controlled synthesis of well-defined polymers via light irradiation. Traditional photoATRP is often limited by the need for high-energy ultraviolet or violet light. These could negatively affect the control and selectivity of the polymerization, promote side reactions, and may not be applicable to biologically relevant systems.

Optimizing photovoltaic performance of squaraine derivative dyes: a DFT study on different anchoring groups.

In this study, we designed squaraine-based dyes with a 2-amino pyrrole donor unit and acene groups like anthracene and pentacene. These dyes incorporate three different electron-withdrawing groups - cyanoacrylate (A1), phosphonate (A2) and boronic acid (A3) - as linkers to the TiO semiconductor. The spectroscopic, electronic and photochemical properties of these compounds were investigated using density functional theory (DFT) and time-dependent density functional theory (TDDFT) simulations.

Hydrophilic Poly(meth)acrylates by Controlled Radical Branching Polymerization: Hyperbranching and Fragmentation.

Topology significantly impacts polymer properties and applications. Hyperbranched polymers (HBPs) synthesized via atom transfer radical polymerization (ATRP) using inimers typically exhibit broad molecular weight distributions and limited control over branching. Alternatively, copolymerization of inibramers (IB), such as α-chloro/bromo acrylates with vinyl monomers, yields HBPs with precise and uniform branching.
