摘　　要：A novel polyurethane polymer containing perylene diimide(PDI)unit and aniline segment,denoted as PU-PDI,was designed and synthesized.Their tensile property and photophysical characteristic were investigated using various experimental and theoretical techniques.It is found that the elongation of PU-PDIs can reach more than 1000%,indicating good tensile performance.Moreover,based on the photoinduced electron transfer mechanism,the aniline segments in polyurethane can quench the auto-fluorescence of PDI unit to a negligible value,which overcomes the intractable fluorescence drawbacks of conventional colour filters.The non-emissive characteristic,in combination with the good thermal stability and tensile property of PU-PDI,provides a feasible design strategy to fabricate optical filters with high display quality.
