WebThe peak chalcone reactivity is at 440 nm which is red-shifted by 25 nm compared to the absorption maximum at 415 nm. The chalcone was attached to a RAFT agent enabling reversible deactivation radical polymerization. The resulting polymer subsequently took part in a photoligation triggered by light from an LED centered at 505 nm.
