AI Technical Summary
Existing photoinitiators such as camphorquinone (CQ) and ITX have migration problems and certain reproductive toxicity, which limits their application in the biomedical field. The development of single-component, low-toxicity photoinitiators has not yet been effectively solved.
A carbazolyl bischalcone photoinitiator is provided, prepared by the Claisen-Schmidt reaction, and used as a single-component photoinitiator or in combination with a hydrogen donor to initiate the polymerization of acrylate monomers, and photocured using an LED light source.
It achieves rapid photoinitiation speed and high double bond conversion rate, enabling it to be used in deep curing systems to prepare thicker polymer materials. It is suitable for the polymerization of various acrylate monomers, including fluorinated monomers, expanding its application prospects in the biomedical field.
