Carbon Dots as a Promising Green Photocatalyst for Free Radical and ATRP‐Based Radical Photopolymerization with Blue LEDs

Carbon dots (CDs) have been used for the first time as a sensitizer to initiate and activate free radical and controlled radical polymerization, respectively, based on an ATRP protocol with blue LEDs. Consideration of diverse heteroatom‐doped CDs indicated that N‐doped CDs could serve as an effective photocatalyst and photosensitizer in combination with LEDs emitting either at 405 nm or 470 nm. Free radical polymerization was initiated by combining the CDs with an iodonium or sulfonium salt in tri(propylene glycol) diacrylate. Polymerization of methyl methacrylate (MMA) by photo‐induced ATRP was achieved with CDs and ethyl α‐bromophenylacetate using CuII as catalyst in the ppm range. The polymers obtained showed temporal control, narrower dispersity ≲1.5, and chain‐end fidelity. The first‐order kinetics and ON/OFF experiments additionally gave evidence of the constant concentration of polymer radicals. No remarkable cytotoxic activity was observed for the CDs, underlining their biocompatibility.

Kohlenstoff-Nanopunkte (CDs) fanden Verwendung als Sensibilisator,u md ie freie radikalischeu nd kontrollierte radikalische Polymerisation auf Basis einer ATRP-Vorschrift mit blauen LEDs zu initiieren und zu aktivieren. Ndotierte CDs sind wirksame Photokatalysatoren und Photosensibilisatoren in Kombination mit LEDs,d ie bei 405 oder 470 nm emittieren. Die Initiierung der freien radikalischen Polymerisation erfolgte durchK ombination von CDs mit einem Iodonium-oder Sulfoniumsalz in Tripropylenglycoldiacrylat. Die Polymerisation von Methylmethacrylat durch photoinduzierte ATRP gelang mit CDs und a-Bromphenylessigsäureethylester unter Verwendung von Cu II als Katalysator im ppm-Bereich. Die erhaltenen Polymere zeigten im betrachteten Zeitfenster eine engere Dispersitätu nd eine Funktionalitätd er Endgruppen bei ATR-Experimenten. Die Kinetik erster Ordnung bestätigt zusätzliche ine konstante Konzentration von Polymerradikalen. Es wurde keine bemerkenswerte zytotoxische Aktivitätder CDs beobachtet, was ihre Biokompatibilitätverdeutlicht.
