Visible Light [2 + 2] Cycloadditions for Reversible Polymer Ligation
Read the full paper here: Macromolecules (2018) DOI: 10.1021/acs.macromol.8b00613 We introduce visible light induced dynamic covalent chemistry as a powerful reversible ligation tool based on a wavelength-dependent photon efficiency analysis (WPEA). We demonstrate by a monochromatic wavelength scan of the reversible dimerization of styrylpyrene at constant photon count that the system is most effective in its forward reaction at 435 nm, while the highest reverse reaction effi
