Chain Versus Ring: Characterization of a Meta‐Phenylene Ladder Polymer and Its Octameric Macrocycle

open access: yesChemistry – A European Journal, EarlyView.
The synthesis and comprehensive spectral and photophysical analysis of a methyl‐substituted ladder meta‐phenylene macrocycle (MeLMMP) and its polymer analogue (MeLPMP) show that, despite differing topologies (macrocycle vs. polymer), both display nearly identical electronic and photophysical properties due to cross‐conjugation.

Toward Larger Cyclo‐9,10‐Anthryleneparaphenylenes

open access: yesChemistry – A European Journal, EarlyView.
During a macrocyclization with a dihydroanthracene diol as corner unit, larger oligomers than the trimer and tetramer were formed and isolated up to the nonamer. Their three‐dimensional structures were studied by X‐ray diffraction. The most abundant macrocycles were rearomatized to the corresponding CPP derivatives.

Slow Release of Bioactive Alcohols From Butenolide Polymers and Coatings

open access: yesChemistry – A European Journal, EarlyView.
In this study we have reported the acid‐mediated release of bioactive alcohols from biobased alkoxy butenolide derived copolymers and coatings. It can potentially be applied for slow release of odors, pesticides, or drug‐related compounds from biobased polybutenolides.

Modelling of continuous low‐temperature emulsion co‐polymerization in 3D‐printed reactor

open access: yesThe Canadian Journal of Chemical Engineering, EarlyView.
A kinetic model for the emulsion copolymerization of butyl acrylate/styrene at low temperatures is proposed and validated against experiments with a redox initiator system. The model was successfully transferred to a 3D‐printed tubular reactor and conversions of more than 80% and small particles sizes below 40 nm were observed.

Xylose Acetals ‐ a New Class of Sustainable Solvents and Their Application in Enzymatic Polycondensation

open access: yesChemSusChem, Volume 18, Issue 6, March 15, 2025.
Novel organic solvents with an unmodified carbohydrate core were synthesised both from D‐xylose and directly from biomass and were successfully used as reaction media for lipase biocatalysts to synthesise aliphatic and aromatic polyesters. Abstract The use of organic solvents in academic research and industry applications is facing increasing ...
