On‐Liquid Surface Synthesis of Crystalline 2D Polyimine Thin Films

open access: yesChemistryEurope, EarlyView.
This work demonstrates the on‐liquid surface synthesis of crystalline 2D polyimine films by leveraging a fluorinated surfactant and a binary solvent mixture of DMAc‐H2O. In situ grazing incidence X‐ray scattering reveals stepwise monomer adsorption, preorganization, and polymerization, accompanied by lattice expansion from 3.4 to 5.3 nm.

Shedding Light on Synthetic Autocatalysis: From Conventional Closed‐Shell Chemistries to Overlooked Open‐Shell Occurrences

open access: yesChemistry – A European Journal, EarlyView.
Why add another catalyst when the product itself holds the power to catalyze its own formation? Autocatalysis in synthetic chemistry enhances reaction efficiency and uncovers novel catalytic behavior across both closed‐shell and open‐shell systems, expanding reactivity and enabling innovative design strategies.

Controlling Aggregation‐Induced Emission by Sterics in Nitrogen–Boron–Nitrogen (NBN)‐Doped Tetraphenylethylene‐Like Molecular Propellers

open access: yesChemistry – A European Journal, EarlyView.
Nitrogen–boron–nitrogen (NBN)‐substituted molecular propellers are presented as structural framework for aggregation induced emission (AIE) applications. Steric hindrance is revealed to steer maximum‐AIE behavior, leading to refined control over assembly‐induced luminescence.

Twisted 1‐ and 2‐Azaperopyrenes: Synthesis, Structure, and Properties

open access: yesChemistry – A European Journal, EarlyView.
ABSTRACT A synthesis of hitherto unknown 1‐ and 2‐azaperopyrenes, twisted nitrogen‐doped peropyrenes, is reported. The synthesis is based on a Brønsted acid‐mediated benzannulation of alkynes. Key alkyne intermediates are synthesized via two complementary routes, including a Pd/C‐catalyzed, copper‐ and amine‐free Sonogashira‐type coupling of (hetero ...
