Electroactive and Photoactive Nanostructured Materials From Self-Assembling Coil-Rod-Coil Triblock Copolymers.
Abstract
Nanoscale materials, devices and systems are currently of wide interest in science and technology. We report a novel approach for preparing functional, electroactive and photoactive nanostructured polymeric materials which uses the inherent phase separation of rod - coil block copolymer systems. A series of novel polyester-polybenzobisthiazole-polyester triblock copolymers was designed, synthesized, and investigated to explore various issues of the self-assembly, solid-state electronic properties and optical properties of nanostructured polymeric materials. The self-assembly or phase separation process as well as the photophysical properties of the resulting nanophase-separated materials are shown to vary with the length of the coil-like block when the electroactive and photoactive rodlike block length is fixed. Because the rodlike blocks are electroactive and photoactive, optical techniques can be used as powerful probes of the self-assembly process and the resulting nanostructures.
