Abstract

A series of fluorescent siloxane-polyurethanes (HPMS-PUs) containing an amino-functionalized, 1,8-naphthalimide, fluorescent monomer (AABD) as a chain extender were synthesized. The properties of the HPMS-PUs were investigated by UV-vis and fluorescence spectroscopies, thermogravimetric analysis and thermal migration behavior. The maximum absorption and emission wavelengths of HPMS-PUs showed a red shift of about 4 nm and a blue shift of about 9 nm, respectively, compared to those of AABD. The Stokes shifts of AABD and HPMS-PU2 were 3514 and 2931 cm^-1, respectively. The quantum yield of HPMS-PU2 was 0.79, which was six times higher than that of AABD. Concentration self-quenching was observed in both AABD and HPMS-PUs. The fluorescence of HPMS-PUs was quite stable with respect to both temperature and fluorescence quencher effects. The thermal stability of HPMS-PUs increased with AABD content. The fluorophore units in the HPMS-PUs did not readily migrate.
