Coordination Chemistry of Boron Subphthalocyanine With BINOL Derivatives: Unexpected Oxidation to Oxa[4]Helicene and Properties of the Resulting Axially Coordinated Complexes Containing Oxa[4]Helicene and/or BINOL Derivatives

Chemistry – A European Journal, EarlyView.
Treatment of BINOL with a boron subphthalocyanine derivative resulted in the formation of a complex coordinated to an oxa[4]helicene derivative, which is generated via a ring‐closure reaction of BINOL. In contrast, treatment of the monomethyl ether of 1,1′‐bi‐2‐naphthol (BINOL) afforded the expected axially coordinated complex.

Multi‐state Photoswitching in Thienoquinoid‐Based Fluorescent Trithiophenes

Chemistry – A European Journal, EarlyView.
A methine‐bridged trithiophene with a thienoquinoid core undergoes photoisomerization of both C═C bonds, affording three geometrical isomers in a ratio controlled by the irradiation wavelength. Despite full π‐conjugation, the system retains fluorescence, enabling wavelength‐addressable multi‐state switching with luminescent readout.

Near‐White Circularly Polarized Luminescence by Color Mixing Utilizing Surface‐Fluorophore‐Modified Cellulose Nanocrystals in Composite Films

Chemistry – A European Journal, EarlyView.
Robust, bio‐derived, and freestanding films based on cellulose nanocrystals (CNCs), covalently decorated with achiral fluorophores, transduce shape chirality and supramolecular helicity into near‐white circularly polarized luminescence (CPL). With composites covering the visible spectrum, near‐white, right‐handed CPL with high luminescence dissymmetry (

Gibbs energy minimization thermodynamics for CO2 capture by aqueous amines: Conservation laws, concentration variables, and parameter consistency

The Canadian Journal of Chemical Engineering, EarlyView.
We clarify how Gibbs‐energy‐minimization models for aqueous‐amine CO2 capture fail when conservation constraints and concentration conventions are inconsistent. Exact standard‐state conversions and Reaktoro case studies show that P(CO2)‐loading fits can mask non‐unique parameters and wrong speciation, motivating complete water‐inclusive formulations ...
