    摘要:
    开发了一系列四[6,7]喹喔啉-四氮杂卟啉锌(6,7-TQP)的合成方法,其外围链通过S、O和N杂原子以及C-C键连接。将 6,7-TQP 的光物理和光化学性质与带有相同外围取代基的四吡嗪并四氮杂卟啉 (TPP) 进行比较,以揭示在吡嗪和四氮杂卟啉部分之间插入苯环的影响。还讨论了 6,7-TQP 组中外围杂原子的影响。与 TPP 相比,制备的 6,7-TQP 的主要吸收带(Q 带)发生了强烈的红移和超色移(在吡啶中 λ max = 730-770 nm,c 高达 500000 dm 3 mol ―1 cm ―1 ) . 它们表现出高单线态氧量子产率(Φ Δ = 0.50-0.74)和相对较低的荧光量子产率(Φ F < 0.08)。

  • Synthesis of .alpha.-ketols mediated by divalent samarium compounds
    作者:Jacqueline Collin、Jean Louis Namy、Frederic Dallemer、Henri B. Kagan
    DOI:10.1021/jo00009a035
    日期:1991.4
    Coupling reactions of acid chlorides are mediated by SmI2 and SmCp2, leading to alpha-ketols 3. Condensation reactions of acid chlorides on aldehydes similarly product alpha-ketols 5; with ketones, best results are obtained with use of SmI2. Reactivities of SmI2 and SmCp2 are compared and mechanisms of the reactions discussed. Formation of an acylsamarium species is shown.

  • REACTANTS FOR CHARGE TRANSFER REACTIONS IN MASS SPECTROMETERS
    申请人:Bruker Daltonik GmbH
    公开号:US20130115711A1
    公开(公告)日:2013-05-09
    The invention relates to the use of substances for the production of anions suitable for charge transfer reactions in mass spectrometers, particularly for the fragmentation of multiply positively charged biopolymer ions by electron transfer or for charge reduction by proton transfer. Diketones, particularly α-diketones, are proposed as a newly found class of substances which can be used both for the production of radical anions for electron transfer dissociations (ETD) with a high yield of fragment ions and also for the production of non-radical anions for the charge reduction of multiply charged analyte ions by proton transfer reactions (PTR). These substances have favorable properties in terms of their handling and the associated analytical methods: they are largely nontoxic, cover a favorable range of molecular masses, and their volatility means that they can be stored in unheated containers outside of the vacuum system, which facilitates the refilling of the containers.
