Abstract
Attachment of azobenzene moieties, substituted with alkyl chains, to a polyglutamate backbone give photochromic ''hairy rod'' polymers, capa ble of forming monolayers at an air/water interface. These monolayers can be transferred to substrates as Langmuir-Blodgett films. Irradiati on and concomitant photoisomerization of the chromophore result in str uctural changes of the monolayers and the LB films, which give the sys tems interesting photoresponsive properties.
