One-dimensional organic photonic heterostructures: Rational construction and spatial engineering of excitonic emission

Abstract

Organic photonic heterostructures are constructed through a template-free self-assembly method. The host-guest intermolecular interactions play an essential role in the formation of various block orange-blue-orange and blue/green microtubes. The spatial distribution of excitons is engineered to investigate the excitonic behaviors in light propagation along the axial heterostructures. These results offer a new route to the integration of organic photonic building blocks for optical processing applications. Copyright © 2012 WILEY-VCH Verlag GmbH & Co. KGaA, Weinheim.
