Construction of and electrophoretic fluorescence imaging with a nano-porous polyaniline-fluorescein conducting particle system.

Electrophoretic fluorescence images have been fabricated by deposition of nanoporous polyaniline-fluorescein conducting particles onto a micro-patterned polyaniline film.

Unusually stable, versatile, and pure arenediazonium tosylates: their preparation, structures, and synthetic applicability.

A new, simple, and effective method for the diazotization of a wide range of arylamines has been developed by using a polymer-supported diazotization agent in the presence of p-toluenesulfonic acid. Various pure arenediazonium tosylates with unusual stabilities can be easily prepared by this method. As a result, these salts are useful and versatile substrates for subsequent transformations, such as halogenation and Heck-type reactions. The unusual stabilities of arenediazonium tosylates are also preliminarily discussed with their X-ray structures.
