Palladium-catalyzed modification of poly(p-bromostyrene) with 4-(phenylamino)azobenzene. Optical properties of new azobenzene group-containing polystyrene

Preparation of New Polymers Containing an Azobenzene Group in the Side Chain by Palladium-Catalyzed Polymer Reaction and Polycondensation and Characterization of the Polymers

“…We have also carried out the Pd-catalyzed polymer reaction of poly( p -bromostyrene- co -styrene) [P( p -BrSt- co -St)] with 1 and the Pd-catalyzed polycondensation of bis(4-bromophenyl) ether with 2 , and a comparison of their optical properties is also reported. Some of the results have been reported in a communication …”

Photofabrication of surface relief gratings from azobenzene containing perfluorocyclobutane aryl ether polymer

“…The PPF polymer was successfully synthesized via a palladium catalyzed amination reaction 48, 49. This reaction is commonly used in the synthesis of triarylamines together with the Ullmann coupling reaction in the presence of copper.…”

Synthesis, characterization, and photochromic properties of PMMA functionalized with 4,4′‐diacryloyloxyazobenzene

“…The thermal cis – trans isomerization of the azobenzene group follows a first‐order kinetics, thus suggesting that the above process is not affected by the presence of adjacent azobenzene chromophores along the macromolecular in either the trans or the cis configuration 22. The slope of plots of ln( A 0 − A t ) against time give the thermal isomerization rate constant ( k T ), where A 0 and A t are absorbances at 337 nm before photoirradiation and after annealing for t min followed by irradiation, respectively 23. Table I also lists the thermal isomerization rate constant at 70°C of the f‐PMMAs.…”
