Diblock copolymers composed of two different polymers spontaneously assemble into periodic nanostructures, of which the size and morphology can be controlled by the molecular weight and composition of copolymers. Their thin films have been utilized for fabrication of nanotemplates to arrange functional materials. Furthermore, these periodic nanostructures can be aligned in specific orientation by directed self-assembly. In this study, we employed nanodomains of diblock copolymers as nanotemplates to fabricate nanopatterns of optically functional materials such as plasmonic gold nanorods and fluorescent organic dyes. Anisotropic nanopatterns were obtained by directed self-assembly of diblock copolymers, from which we were able to organize nanorods and fluorophores into anisotropic nanopatterns. The anisotropic nanopatterns were also transferred onto other substrates and their optical properties were characterized. |
