-甲基哌啶

The bay area has no substituent and has electron-withdrawing groups,such as bromine atom,cyano-group and 4-formyl phenoxy group compounds have strong absorption in 525 nm,when excitated them,they have strong yellow and salmon pink luminescence bettwen 538 and 566 nm.When introduce electron-donating substituents,such as phenoxy group,morpholinyl,piperidinyl and n-butylamino group,the absorption bathochromic shift while the electron-donating ability is improved,bettwen 536 and 692 nm have strong absorption,reach to the near-infrared region. When excitated them,only the phenoxy group compound has strong salmon pink luminescence in 572 nm,the others have no fluorescence.

其中，港湾位无取代的以及含吸电基团(—Br、—CN、对甲酰基苯氧基)化合物在525 nm左右处均有很强的吸收ε＞10~4M~(-1cm~(-1)，当光激发时，港湾位无取代、溴代和氰基取代物发出538～547 nm的强烈黄色荧光，对甲酰基苯氧基取代物则发出566 nm的强烈橙红色荧光；含供电基团(苯氧基、吗啉基、哌啶基、正丁氨基)化合物随着供电子能力的增强，吸收发生红移，在536～692 nm处均有很强的吸收ε＞10~4M~(-1cm~(-1)，达到了近红外区，当光激发时，只有苯氧基取代物发出572 nm的强烈橙红色荧光，而含氮供电基取代物均发生了荧光淬灭。
