Photopolymerization of aniline derivatives in solid state and its application

Novel Multifunctional Polymers from Aromatic Diamines by Oxidative Polymerizations

“…87 The most wondrous feature of the photooxidative polymerization is that this polymerization can be successfully carried out when the monomer N-phenyl-pPD exists in the solid state as compared with the other three oxidative polymerizations. 206 Note that the PAN obtained has a lower polymerization yield and lower molecular weight than that by the chemically oxidative polymerization from N-phenyl-pPD and/or AN. 207 One of the greatest advantages of electropolymerization is that almost all aromatic diamines listed in Scheme 1 and Tables 3 and 4 are applicable for polymerization.…”

“…Photooxidative polymerization of N-phenyl-pPD in the solid state has been studied by Kim in 2001. 206 It is found that the solid-state photopolymerization with Flemion film containing tris(2,2′-bipyridyl) ruthenium and N-phenyl-pPD is successful, 258 indicating success on the photoinduced electron transfer between tris(2,2′-bipyridyl)ruthenium and N-phenyl-pPD even in the solid state. Note that a trace amount of water (ca.…”

“…255 Only recently have there been a few publications on the photocatalyzed oxidative polymerization of two pPD derivatives including N-phenyl-pPD and 2,3,5,6-tetramethyl-pPD. 87,205,206,256,257 The photocatalyzed oxidative polymerizability of other aromatic diamines has not been reported.…”

“…Upon illumination in the visible region of 420-600 nm with a 500 W xenon lamp through UV and IR cutoff filters, a well-defined photoimage or micropattern with less than 1 mm has been successfully obtained by a solid-state photooxidative polymerization with Flemion film that was prepared by casting the Flemion solution containing ruthenium trisbipyridyl and methyl viologen ions as well as N-phenyl-pPD on glass under dark. 206 The PAN photopolymerized thus exhibits a conducting state because the micropattern is green in color. It is believed that using a laser rather than a xenon lamp will form a much finer micropattern.…”

Film Chemistry Control and Growth Kinetics of Pulsed Plasma-Polymerized Aniline

“…The chemical or electrochemical routes are still the most common syntheses of polyaniline. However, some other preparations have been prospected like the inverse emulsion [1], autocatalytic [2], enzymatic [3], or photochemical [4] polymerization.…”
