Exploiting the tetrazine-norbornene reaction for single polymer chain collapse

摘要

Single chain polymer nanoparticies (SCNPs) have been formed using polystyrenes decorated with pendent norbornenes and a Afunctional tetrazine crosslinker. Characterisation by size exclusion chromatography and ~1H NMR gives evidence for the formation of SCNPs by the tetrazine-norbornene reaction, whilst light scattering, neutron scattering, transmission electron microscopy and atomic force microscopy show that discrete well-defined nanoparticies are formed and their size in solution calculated.
