Push–pull benzophenone derivative-based visible photoinitiating systems: synthesis, characterization, properties, and application for free radical photopolymerization under LEDs

Key Points

• The aim is to synthesize and characterize benzophenone derivatives for use in visible photoinitiating systems.
• Synthesis of non-coplanar benzophenone derivatives
• Characterization of the chemical properties
• Evaluation of photoinitiation under LED exposure
• Non-coplanar benzophenone derivatives effectively sensitize light for photoinitiation
• Achieved successful free radical photopolymerization using visible light
• Demonstrated enhanced efficiency compared to traditional systems
