Highly emissive poly(maleic anhydride-alt-vinyl pyrrolidone) with molecular weight-dependent and excitation-dependent fluorescence

Abstract

Nonconventional poly(maleic anhydride-<italic>alt</italic>-vinyl pyrrolidone) copolymers exhibit distinct AIE characteristics, as well as molecular weight-dependent and excitation-dependent fluorescence. They can emit blue to red colours under different excitation wavelengths.
