TL;DR: In this article, a review of recent progress in applications of photoinitiators and sensitive photo-initiating systems under visible lights is reported, and their relative efficiencies in the photopolymerization of different monomers are exemplified and discussed.

TL;DR: In this article, the authors focused on the recent developments in LED technology, allowing the design of novel and efficient light sources for the free radical and cationic photopolymerization of various monomers, the synthesis of interpenetrating polymer networks (IPNs) or thiol-ene photopolymers, and the development of novel photoinitiators and photo-initiating systems specifically adapted for LED excitation.

TL;DR: In this article, seven naphthalimide derivatives with different substituents have been designed as versatile photoinitiators (PIs), and some of them when combined with an iodonium salt or an amine (and optionally chlorotriazine) are expected to exhibit an enhanced efficiency to initiate the epoxides and the free radical polymerization of acrylates under different irradiation sources.

TL;DR: Different polyaromatic structures (truxene derivatives and tris(aza)pentacene) are presented as new metal-free organic photocatalysts (OPC) to promote free radical polymerization FRP and ring-opening polymerization (ROP) under halogen lamp, household LED bulb, and laser diode (405 nm) as discussed by the authors.

TL;DR: In this paper, the photoredox catalysis approach is used to initiate the free radical promoted cationic photopolymerization of N-vinyl carbazole (NVK) under very soft irradiation conditions (halogen lamp, blue or green LED bulbs) using visible-light harvesting photocatalysts (mainly Ir(III) complexes) in iodonium salt and silane containing photoinitiating systems.
