Deep learning application for stellar parameter determination: III-denoising procedure

Open Astronomy
In this third article in a series, we investigate the need of spectra denoising for the derivation of stellar parameters. We have used two distinct datasets for this work. The first one contains spectra in the range of 4,450–5,400 Å at a resolution of 42,

Helical Folding of Abiotic Chiral Poly(phosphodiester)s

Chemistry – A European Journal, EarlyView.
Design and structural analysis of a new class of phosphodiester foldamers are presented. These oligomers that fold into single helical architecture showed length and temperature stability dependence comparable to DNA duplexes. ABSTRACT Functions of biomolecules are intimately linked to their structures which result from the folding of a linear sequence

Asymmetric Diphosphane Dioxides With A–π–A–π’–D Scaffolds for High‐Purity Deep‐Blue Luminescence

Chemistry – A European Journal, EarlyView.
Diphosphane dioxide‐based luminophores with donor–π–acceptor– π’–acceptor scaffold enable efficient deep‐blue emission from tunable charge‐transfer states affording high photoluminescence up to 95%. OLEDs reach EQE 4.9%, aided by triplet–triplet annihilation, highlighting a practical route to high‐performance blue emitters.

Post‐Modification of Tripyrenylenes to Enantiopure π‐Extended D3‐Symmetric Propellers

Chemistry – A European Journal, EarlyView.
The post‐modification of tripyrenylenes to π‐extended enantiopure propellers with tris‐phenanthrophenazines is presented and the chiroptical properties as well as the solid‐state packings investigated in comparison to the corresponding racemic mixtures.

Conformational dynamics of the pyrene excimer

Physical Chemistry Chemical Physics
We characterized the S 1 state PES of the pyrene dimer, revealing key excimer conformations. A rapid shift to a stacked-twisted form dominates the excimer's structure and fluorescence.

Mechanistic Insights Into Sustainable Catalytic Pyrolysis of Biomass‐Derived Ferulic Acid: The Role of Alumina Regeneration

Chemistry – A European Journal, EarlyView.
Surface‐bound ferulate phenolate complexes undergo styrene‐like polymerization on alumina, yielding a polymeric carbonaceous layer that progressively transforms into polyaromatic carbon domains with concomitant release of aromatic products, while parallel surface‐assisted decarboxylation produces 4‐vinylguaiacol. ABSTRACT A fundamental understanding of

Benzo[c][1,2,5]Thiadiazole Linkers Enhance the Effectiveness of Cavity‐Containing Supramolecular Photocatalysts

Chemistry – A European Journal, EarlyView.
Seven novel supramolecular photosensitizers based on benzo[c][1,2,5]thiadiazole (BTZ) tethered to calix[4]arene (C[4]) scaffolds are reported with facile, scalable, and selective syntheses. Their abilities to produce singlet oxygen have been tested through the photo‐oxidation of α‐terpinene.

Chiral Display of Pyrenes on a Peptoid Backbone: Conformational Homogeneity of Peptoid Controls Excimer Chirality

Small Structures
Controlling chromophore chirality in three‐dimensional space is crucial for understanding the structure–chiroptical relationship. Such control enables the prediction of ideal materials for use in chiral photonic applications.
