Supplementary information files for Aminomaleimide fluorophores: a simple functional group with bright, solvent dependent emission

Supplementary files for Aminomaleimide fluorophores: a simple functional group with bright, solvent dependent emission. Amino-substituted maleimides form a new class of highly emissive compounds, with large Stokes shifts (>100 nm) and high quantum yields (up to ∼60%). Emission is responsive to the maleimide's environment with both a red-shift, and quenching, observed in protic polar solvents. Aminomaleimides are easily functionalised, providing a versatile fluorescent probe.
