It is believed that azobenzene amphiphiles tend to be strongly H-aggregated during pure Langmuir-Blodgett (LB) film manipulation and therefore they are unable to photoisomerize. However, we present in this article the manner for destabilizing such aggregation by means of a simple physical treatment process, obtaining finally well photoresponsive amphiphilic azobenzene in the pure LB films. Such LB films are highly suitable for regulating the orientation and photoreactivity of other surface-in touch systems such as nematic liquid crystals and photoreactive monomers to be polymerized. Therefore, we investigated the manipulation of LB films of the azobenzene derivative, 11-(4-(4-hexyl-phenylazo)-phenoxy)-undecanoic acid using different monomeric isomers, by temperature and monolayer transfer methods. The LB films were then exposed to heat treatment process and finally to photophysical processes. |
