Extended Data Fig. 4: Fluorescence spectra of solution samples.
From: Near-identical macromolecules spontaneously partition into concentric circles
a–b, Fluorescence spectra (λext = 488 nm) of MePEG5KNBD (green curve, a), MePEG5KRhB (red curve, a), and a 3:1 mixture of MePEG5KNBD and MePEG5KRhB (black curve, b) in water. Combined spectrum (black broken curve, a) resulting from summing the spectral data of individual PEG. c–d, Fluorescence spectra (λext = 488 nm) of MePEG5KNBD (green curve, c), MePEG5KRhB (red curve, c), and a 3:1 mixture of MePEG5KNBD and MePEG5KRhB (blue curve, d) in aqueous (NH4)2SO4 solution (26.4 wt%). Combined spectrum (blue broken curve, c) resulting from summing the spectral data of individual PEG.
