    摘要:三种硫代碳青霉素染料,3,3'-二甲基硫代碳青霉素碘化物(dmtcc),3,3'-二乙基硫代碳青霉素碘化物(detcc)和3,3'-二丙基硫代碳青霉素碘化物(dptcc)在微晶纤维素上的光物理学研究,浓度范围为5.0.10-4至10.0 μmol G-1.使用基态漫反射吸收技术,仅检测到所有探针的h聚集物形成.形成的聚集物量取决于样品的水合度,始终随着样品干燥而减少.所有吸附染料的荧光量子产率比在非粘性溶剂中观测到的高一个数量级,Dmtcc为0.98,Detcc为0.96,Dptcc为0.63.记录了激光诱导的荧光发射(使用增强电荷耦合器件检测系统),作为激光功率的函数,结果显示对于受高激光强度照射的干燥浓缩样品,检测到了第二个荧光发射带(相对于单体发射的巴托克移位).这种发射显示对激光功率的超线性依赖.这里检测到的新发射来自通过单体的荧光异构体形成的,通过双光子吸收过程.

    标 题:Dye intermediates and their preparation and use in the synthesis of methine dyes
    发明人：OWEN JOHN R
    权利人:EASTMAN KODAK CO
    摘要:Compositions of matter are provided comprising a stable, non-vaporous monomeric methylene base selected from a 2-methylenethiazoline; a 2-methylenebenzothiazoline; a 2-methylenenaphthothiazoline; a 2-methylenebenzoselenazoline; and a 2-methylenenaphthoselenazoline. The compositions of the invention are prepared by reacting the parent 2-methyl quaternary salt with a non-hydroxylic base which removes a proton of the heterocyclic salt together with a proton acceptor which inhibits build-up of the hydro salt of the non-hydroxylic base, the reaction being conducted under anhydrous conditions in a non-hydroxylic liquid in which the heterocyclic quaternary salt is sufficiently insoluble to inhibit dimer formation. The compositions of the invention are employed in the preparation of methine dyes.
