摘　　要：设计合成了一种萘酰亚胺衍生物,并通过接枝螺吡喃成功制备了具有多重荧光的光致变色分子NA-SP。通过红外光谱、核磁共振氢谱和碳谱,以及质谱对其结构进行表征,探究了其光致变色及荧光发射性能,结果表明化合物NA-SP表现出对紫外光敏感且快速的响应。将NA-SP单独或与液体分散蓝B-354拼色用于涤纶织物染色,可制备出具有光致变色及荧光变色的多功能变色纺织品。经过10次光照循环周期,多功能变色纺织品仍然保持良好的光响应性能,在开发智能变色面料及防伪领域具有一定的应用价值。A naphthalimide derivative is designed and synthesized,and a photochromic molecule NA-SP with multiple fluorescence is successfully prepared by grafting with spiropyran.The structure of NA-SP is characterized by IR,1HNMR and 13CNMR spectra,and mass spectrometry.The photochromic and fluorescence emission properties of NA-SP are investigated,and the compound NA-SP exhibits UV photosensitivity and rapid response.When NA-SP is applied to polyester fabric dyeing alone or compound with liquid Disperse Blue B-354,photochromic and fluorescent multifunctional fabrics can be achieved.After 10 illumination cycles,the fabrics still maintain good light response performance.It has certain application value in developing intelligent color-changing fabrics and anti-counterfeiting fields.
