Microwave-enhanced reactions are very fast in comparison to thermal reactions. They are often finished within a few minutes. Thus, the determination of the end point often fails, because conventional analytical methods are too slow. We developed a fast method using a UV/Vis sensor, which allows a direct online monitoring of the reaction process. The potency of the method is demonstrated by means of five representative reactions.

A highly efficient one-pot procedure for the preparation of fluorescein-based dyes with relatively high yield was investigated. Significantly, introduction of these fluoro and chloro functional groups and forming host-guest complexes with cyclodextrins partially enhanced the photostability of these dyes. A highly efficient one-pot synthesis of fluorescein-based halogenated dyes with relatively high yield was reported. Introduction of fluoro and chloro functional groups and forming host-guest complexes with cyclodextrins enhanced their photostability. Copyright

Four kinds of ring-fluorinated fluoresceins and sulfofluorescein from tetrafluororesorcinol and/or tetrafluorophthalic anhydride have been synthesized and the photochemical properties of the zinc oxide nanocrystalline electrode sensitized by the ring-fluorinated fluoresceins were investigated.

The family of dyes of the invention are fluoresceins and rhodols that are directly substituted on one or more aromatic carbons by fluorine. These fluorine-substituted fluorescent dyes possess greater photostability and have lower sensitivity to pH changes in the physiological range of 6-8 than do non-fluorinated dyes, exhibit less quenching when conjugated to a substance, and possess additional advantages. The dyes of the invention are useful as detectable tracers and for preparing conjugates of organic and inorganic substances.
