光致变色染料

光致变色染料光致变色光致变色是一种可逆的化学反应，这是一个重要的判断标准．在光作用下发生的不可逆反应，也可导致颜色的变化，只属于一般的光化学范畴，而不属于光致变色范畴MnCOCONCNMnCOCONNCVisUV光致变色化合物种类俘精酸酐OOOR1R2R3OOOR2R3R1OOOR2R3R1UVUVUVVisz-E-formC-formform俘精酸酐合成OC2H5OC2H5OOONaHOC2H5OHOOC2H5OHOC2H5OC2H5OOOC2H5OC2H5OOONaHOC2H5OHOOKOHHClOHOHOOCH3COClOOOH2SO4俘精酸酯希夫碱OHN365nm436nmNOHRR'RR'OHCHOR1H2NR2C2H5OHOHR1NR2苯并吡喃OOCH3OCH3OOOH3COOHO(CH3CO)2OCH3COONaOH3COOOH3COOHOH3COOCOCH3OHOOHNaOHOHOOH十二烷基苯磺酸钠OOH2SO4偶氮苯NNRR'NNRR'365nm460nmorheat合成NH2NNRNNRNORH2NNO2R2ZnNaOH/CH3OHNNRR苯氧基蒽醌OOOOOOhvhv'合成OOOOHH3BO3OOOHPCl5OOClClPhOHOOOOH2SO4POCl5K2CO3OOOOHH3BO3PCl5OCOOHOHOCOClClH2SO4H2SO4OClOPhOHOOOK2CO3螺吡喃NONO2NNO2Ohv1hv2orheatClosed-formOpen-formNOHORR'RR’λmax/nm颜色变化1HH385无色红色2HBr290无色红色3BrBr285无色红色4ClH290无色红色5HCl292无色红色6ClCl290无色橘黄7BrNO2550浅黄色草绿色NOHORR'RR’λmax/nm颜色变化8NO2Br550橘黄墨绿色9ClNO2560浅黄色草绿色10NO2Cl530橘黄褐红色11NO2NO2510浅黄色紫色吲哚部分的合成螺噻喃螺噁嗪异构态经典合成HONOHNHONONNHONONNONNNNONNHONNaNO2HClHONNOHONNOOBr2OBrNH2NNNHONONONNNNHONONONNNNHONONONNSNSNNONONOHEtOHreflux1h双体合成OBr2OBrNH2NNNHONONONNNNHONONONNNNHONONONNSNS二氢芘hvhv'VisUVVisUVVisUVC-CC-OO-O合成ClOClCH3MgIMglClClOClClIINaCH3COOHUVOOOOOHOOOO杂环二芳基乙烯类二噻吩乙烯合成SSHCHOHClCH2ClNaCNSNCCCl4NaOH,Bu4NBrSNCCNSNaOHSSOOOSClClOOSOOSTiCl3(THF)3SSAlCl3光致变色染料应用光存储分子开关分子导线变色眼镜变色玻璃……光存储技术非破坏性读出近红外折射率变化荧光读出光控分子开关光控分子导线FFFFFFSSFFFFFFSSUVVisCNCNSSSSCNCN2-open2-closed多变色团多色彩光致变色材料M.Irie,etal.,Angew.Chem.Int.Ed.,2003,42,3537全彩变色K.Matsuda,IrieM.etal.,JACS.,2005,127,8922MolecualrCushionforIsomerizationR.A.Evans,etal.,NatureMater.,2005,4,249and193光控阀门光致变色液晶变色镜片变色玻璃变色漆
