Cost-effective and simple synthesis
The photoinitiator should be economical to produce with a straightforward and scalable synthesis process.
Non-toxic and odorless
Both the photoinitiator and its photolysis products should be non-toxic and odor-free, ensuring safe handling and suitability for indoor and consumer applications.
Good stability and storage performance
The photoinitiator should exhibit excellent thermal and chemical stability, allowing for long-term storage without degradation.
Spectral compatibility
The absorption spectrum of the photoinitiator must closely match the emission spectrum of the radiation source and possess a high molar extinction coefficient to ensure efficient light absorption.
Efficient excited-state transition
Upon light absorption, the photoinitiator should efficiently transition to the excited singlet state and undergo rapid and effective intersystem or reaction pathways.
High initiation efficiency
The photoinitiator should generate reactive species (radicals or cations) with high quantum yield, enabling fast polymerization rates, shorter curing times, and reduced initiator dosage.
