We are thrilled to announce that our LIDER‑funded research article—“Less is more: innovative cationic initiators effective in visible light photopolymerization”—has been published in the Chemical Engineering Journal (IF 13.3, Ministerial Points: 200).
This study, led by Monika Topa-Skwarczyńska, Katarzyna Starzak, Mariusz Galek, Izabela Mirek, Małgorzata Tyszka‑Czochara, Jaroslav Lukes, and Joanna Ortyl, introduces a novel class of iodonium salts derived from biphenyl structures. These have been carefully designed to match the emission wavelengths of 3D printer LEDs while maintaining transparency (“less is more”)—an optimal balance of high efficiency under visible light and minimal coloration.
Key findings include:
âś… Effectiveness in both cationic and radical photopolymerization, confirmed via real-time FT-IR
🦷 Low cytotoxicity, meeting ISO 10993-5 standards across multiple cell lines
🖨️ Excellent performance in high-resolution 3D printing—outperforming conventional initiators like SpeedCure 938
These initiators are also ideally suited for dental composites, offering improved hardness and elasticity—proving their versatility for light-curing applications
This achievement underscores our commitment to creating safer, greener, and more efficient photoinitiators for advanced applications in polymer engineering. 🔬
