摘要
苊经发烟硝酸硝化，稀硝酸氧化得到６，７－二硝基－１Ｈ，３Ｈ－萘并［１，８－ｃｄ］吡喃－１，３－二酮，它与２，４－二甲基苯胺缩合后用氯化亚锡还原得到６，７－二氨基－２－（２′，４′－二甲基）苯基－１Ｈ－苯并［ｄｅ］异喹啉－１，３（２Ｈ）－二酮。与６－氨基－２－（２′，４′－二甲基）苯基－１Ｈ－苯并［ｄｅ］异喹啉－１，３（２Ｈ）－二酮（Ｃ．Ｉ．溶剂黄４４，或Ｃ．Ｉ．分散黄１１）相比，其在ＤＭＦ中的最大吸收波长红移了１７．６ｎｍ，最大荧光波长蓝移了４２．７ｎｍ，荧光量子产率有所增大。
Acenaphthene is nitrated by fumic nitric acid,the resultant is then oxidized by diluted nitric acid(65%)to produce 67 dinitro 1H3H naphtho[18 cd]pyran 13 dione(Ⅰ),which is condensed with 24 dimethylanilin to form 67 dinitro 2 (2′4′ dimethyl)phenyl 1H benzisoquinolin 13(2H) dione(Ⅱ).The title compound is obtained by the reduction of Ⅱ with stannous chloride in acidic media.Compared with 6 amino 2 (2′4′ dimethyl)phenyl 1H benzisoquinolin 13(2H) dione(C.I.Solvent Yellow 44,or C.I.Disperse Yellow 11),the maximum absorbing wavelength shifts 17 6 nm bathochromically but the maximum fluorescence wavelength shifts 41 7 nm hypsochromically,and its fluorescence quantum yield is increased.
