The practicality of radical polymerizations is limited by their sensitivity to O2. This inhibitor can be enzymatically degraded into H2O2, which is scavenged by pyruvate as part of a new atom transfer radical polymerization (ATRP) methodology.
Semiconductor nanocrystals absorb light and are involved in energy transfer to and from surface chromophores. Tuning the nanocrystal- and chromophore-centred exciton energies affords exquisite control over an excited-state equilibrium.
