Quantum‐Engineered Magnesium Phthalocyanine for Multifunctional Optoelectronics: Charge Transfer Dynamics, Topological Features, and Device‐Level Integration

ChemistrySelect, Volume 11, Issue 38, 13 October 2026.
ABSTRACT Magnesium phthalocyanine (MgPc) is investigated as an organic semiconductor through a combined theoretical and experimental approach. Density functional theory (DFT) and time‐dependent DFT calculations reveal a moderate HOMO‐LUMO gap (2.16 eV), pronounced π→π* and intramolecular charge‐transfer transitions, and a low exciton binding energy (0 ...

[O─I─O]+ Halogen‐Bonded Complexes of Pyridine N‐Oxides

Angewandte Chemie, Volume 138, Issue 40, 28 September 2026.
The missing puzzle of 3‐center‐4‐electron halogen‐bonded complexes viz. [O─I─O]+ of pyridine N‐oxides are structurally characterized by x‐ray diffraction. Monodentate N‐oxide O‐atom acts as the halogen bond acceptor. Their solution complexations are characterized by 15N NMR spectroscopy.

Alkali Chalcogenido Dialuminates A6[Al2Q6] (A = K, Rb, Cs; Q = S, Se, Te)

Zeitschrift für anorganische und allgemeine Chemie, Volume 652, Issue 15, 1 October 2026.
Seven new alkali chalcogenido aluminates A6[Al2Q6] (A = K‐Cs, Q = S‐Te) complement the family of simple metallates(III) A6[M2Q6] (M = Al‐In, FeIII) with dinuclear anions of two edge sharing [AlQ4] tetrahedra. Despite the similar anions, straightforward bonding situation and physical properties, these metallates crystallize in seven different structure ...

Ambiphilic Ligand Stabilization of Aluminum(I) Fragments: Halides, Cations, and a Hydride

Angewandte Chemie, Volume 138, Issue 40, 28 September 2026.
Stabilization of elusive aluminum(I) halides in the framework of an ambiphilic ligand is reported. The unique bonding situation at the trigonal‐bipyramidal aluminum center is analyzed, and the coordination chemistry and Al(I)Br transfer reactivity of the complexes are presented.

Capturing Non‐Linear Neighborhood Structure: An Autoencoder Approach to Census‐Based Dimensionality Reduction for Residential Differentiation

Geographical Analysis, Volume 58, Issue 4, October 2026.
ABSTRACT Dimensionality reduction is fundamental to applied spatial data analysis, condensing high‐dimensional indicators into parsimonious representations for mapping and modeling. Principal component analysis (PCA) remains a dominant approach, yet its linearity assumptions constrain its capacity to capture the complex, non‐linear dependencies ...

Mutual antagonism between auxin and diacylglycerol acyltransferase 2 regulates high‐temperature‐induced hypocotyl elongation

New Phytologist, Volume 252, Issue 1, Page 222-240, October 2026.
Proposed model for auxin–DGAT2 crosstalk regulating high‐temperature‐induced hypocotyl elongation. Summary Cell elongation is a fundamental process in plant growth and development, and it is significantly affected by temperature changes. While the signaling mechanisms driving high‐temperature‐induced cell elongation have been extensively studied, the ...
