Structure investigations of binary azeotrope of diethyl amine–acetone by FT-IR and 1H NMR spectroscopy

The article shows results of FT-IR and 1H NMR study for azeotrope diethyl amine–acetone. Changes in chemical shifts and vibrational frequencies for pure diethyl amine, pure acetone and their azeotrope were obtained. The unit-structure of cluster has been

The Raman, IR and NMR of Ethanechalcogenols [PDF]

, 1977
One would expect C2H5-X-H to belong to point group Cs, if C2H5-X-H has the highest symmetry. The number, species and activity of the fundamentals of C2H5-X-H on the assumption of the Cs structure is 13A′(R, p; IR)+8A"(R; IR). However the obtained spectra

Phosphor‐Sensitized Ternary Organic Solar Cells Achieving 18.6% PCE via Ir(III)‐Mediated Triplet Energy Transfer and Non‐Radiative Recombination Suppression

Advanced Science, EarlyView.
A synergistic phosphor‐sensitization strategy (PSS) significantly enhances ternary OSCs performance. By integrating an Ir‐3 complex as a triplet energy mediator within a pyrazine‐based (N2) ternary blend (PM6:N2: L8‐BO) doped with 1 wt.% of Ir‐3 complex, and a PCE of 18.6% is achieved through efficient triplet‐triplet energy transfer (TTET), suppressed

Mechanochemical Engineered Sulfur Copolymers Onto Group 13 and Related Fillers Through Lewis Acid‐Base Pairing

Advanced Science, EarlyView.
Green mechanochemical copolymerization was developed for universal interfacial modification of Group 13 and related fillers. By leveraging Lewis acid–base coordination to anchor sulfur‐containing polymers—validated via multiscale characterization and DFT—this versatile method boosts performance across liquid fuels, thermal‐shielding materials, and ...

Ionically Counter‐Programmable Phase‐Separation of Superstable Star‐Biopolyamide Coacervates for Electrothermally‐Responsive Pseudosolid Smart Windows

Advanced Science, EarlyView.
We develop bio‐based, star‐branched polyamides from itaconic acid and cadaverine with tunable lower critical solution temperature (LCST) transitions for dynamic solar modulation. Specific metal ion coordination with pyrrolidone moieties drives precise phase transitions via calcium‐induced salting‐in and sodium‐induced salting‐out mechanisms. Formulated

H‐Bonding‐Induced Repulsion Between Small Groups Toward a Highly Puckered Benzene

Advanced Science, EarlyView.
A benzene derivative bearing methylamino and nitro substituents adopts a boat‐shaped ring conformation. Comparison with four related compounds supports a role for intramolecular hydrogen bonding in constraining substituent orientations and promoting local steric crowding associated with ring puckering.
