Facile Access to N‐Substituted Pyridyl Ligands

Advanced Synthesis &Catalysis, Volume 368, Issue 9, 5 May 2026.
A modular, robust, and versatile Buchwald–Hartwig amination protocol that enables the rapid synthesis of bipyridine, phenanthroline, terpyridine, and pybox ligands bearing dialkylamine, diarylamine, and heteroaromatic N‐substituents. Pyridyl motifs equipped with N‐substituents can be powerful ligands for catalysis, yet their broader adoption is limited

Predicting solar cell efficiencies using historical data from a manufacturing process

The Canadian Journal of Chemical Engineering, Volume 104, Issue 5, Page 2401-2415, May 2026.
Abstract The solar cell manufacturing data of a passivated emitter and rear cell solar cell manufacturing plant was studied to assess the effects of tool usage and the processing time spent on each tool on the solar cell efficiency. Since manufacturing processes involve several steps with multiple tools, tracing their quality parameters back to the ...

Sterically Controlled Interfacial Charge‐Transfer Mechanisms in Unsymmetrical Squaraine Dyes for Suppressed Aggregation and Enhanced Performance in High‐Efficiency Dye‐Sensitized Solar Cells

ChemistryOpen, Volume 15, Issue 5, May 2026.
Molecular engineering of cis‐configured unsymmetrical squaraine dyes reveals how branched alkyl substituents regulate aggregation and interfacial charge–transfer processes on TiO2. Steric shielding suppresses H‐type aggregation and retards interfacial recombination, leading to enhanced recombination resistance and improved open‐circuit voltage.

Interfacial Enrichment and Demetallation of a Zinc Porphyrin in the Ionic Liquid [C4C1Im][PF6]

ChemPhysChem, Volume 27, Issue 8, 28 April 2026.
Upon dissolution of zinc porphyrins with long dodecyl chains in the ionic liquid [C4C1Im][PF6], partial [PF6]‐ hydrolysis occurs along spontaneous porphyrin demetallation. Driven by their buoy‐like chains, the free‐base porphyrins extremely enrich at the outermost surface as proven by angle‐resolved X‐ray photoelectron spectroscopy, an interesting ...

Unveiling the Photophysical Properties of Indole‐Containing Boron Complexes: Exploring Intramolecular Charge Transfer Character, Tunable Emission, and Large Stokes Shifts

ChemPhysChem, Volume 27, Issue 8, 28 April 2026.
Indolyl‐imine–based NN complexes were synthesized and investigated to clarify how structural modification tunes intramolecular charge transfer (ICT), resulting in large Stokes shifts and tunable emission properties. Steady‐state and ultrafast spectroscopy, supported by density‐functional theory (DFT), showed that altering peripheral phenyl groups ...
