摘要:通过 Wittig 反应合成了二-1-萘基和二-2-萘基多烯(in,N=1-4,6 和 In',N=1-6).萘醛(iii 和 Iii'),3-萘基-2-丙烯醛(v 和 V'),5-萘基-2,4-戊二烯醛(vi 和 Vi')和粘液醛被用作羰基成分.合成了萘甲基三苯基卤化鏻(iv 和 Iv'),3-萘基-2-丙烯基三苯基溴化鏻(xi 和 Xi')和 5-(2-萘基)-2,4-戊二烯基三苯基溴化鏻(xii'),并通过与苯基锂反应转化成相应的膦.羰基与膦烷通过适当的组合反应生成了二萘基多烯(in 和 In').二-1-萘基多烯(in)的电子光谱显示出宽阔的无结构吸收曲线.相反,二-2-萘基多烯(in')的吸收曲线则表现出明显的振动精细结构.研究发现,随着双键数(n)的增加,最长波长峰(λmax)的浴色偏移可以用以下经验公式表示:λmax=45.4N0.7+302(四氢呋喃中的纳米数)

标 题 :Ethenyl-substituted dipyrrometheneboron difluoride dyes and their synthesis

摘要:This invention relates to ethenyl-substituted derivatives of dipyrrometheneboron difluoride dyes that have an absorption maximum at wavelengths longer than about 525 nm, and are electrically neutral, highly photostable and, in most cases, highly fluorescent with relatively narrow absorption and emission spectra. The ethenyl-substituted dyes generally have the structure: wherein at least one of the fluorophore substituents R1-R7, is an ethenyl group of the formula -CXm=CYm-Zm, where m is any combination of locations 1, 2, 3, 4, 5, 6, and 7 corresponding to the location of parent fluorophore substituents R1-7. The initial ethenyl substituents Xm, Ym, and Zm, which may be the same or different, are halogen, alkyl (containing 1-10 carbon atoms), cyano, ester, amide, ethenyl or polyethenyl, aryl or heteroaryl. The non-ethenyl substituents, which may be the same or different, are hydrogen, halogen, alkyl (containing 1-18 carbon atoms), aryl, arylalkyl, heteroaryl, acyl or sulfo.
