The aliphatic polyurethane with pendant anthracene moieties (PU-anthracene) was prepared from polycondensation of anthracen-9-yl methyl 3-hydroxy-2-(hydroxymethyl)-2-methylpropanoate (anthracene diol), 1 with hexamethylenediisocyanate in the presence of dibutyltindilaurate in CH2Cl2 at room temperature for 10 days. Thereafter, the PU-anthracene (Mn,GPC = 12,900 g/mol, Mw/Mn = 1.87, relative to PS standards) was clicked with a linear -furan protected-maleimide terminated-poly(methyl methacrylate) (PMMA-MI) (Mn,GPC = 2500 g/mol, Mw
