Organic photonic nanostructures

Research output: Chapter in Book/Report/Conference proceedingChapter


Conjugated organic materials are relevant to functional photonic nanostructures because of their rich molecular structure-processing-property relationships and their propensity for strong, visible-frequency excitonic transitions. The most common organic photonic nanostructures are nanoparticles, nanowires, and nanofibers made from conjugated organic small molecules or conjugated organic polymer materials. The range of functions demonstrated at the nanoscale using organic photonic nanostructures include lasing, polarized light emission, electroluminescence, photodetection, chemical sensing, and biosensing. The optical properties and functionality of organic photonic nanostructures can differ from (and, in some cases, can be enhanced compared to) thin film and bulk samples of the constituent organic material, which can lead to optical anisotropies and changes in intramollecular or intermolecular interactions. Photon emission has been shown to be both enhanced and quenched in different types of nanoscale organic aggregates and band gaps also can vary in a nonpredictable manner with organic nanostructure size. In this chapter, size dependence, fabrication, characterization, and photonic properties of conjugated organic nanostructures (both small molecule and polymer) are discussed, along with case studies of selected photonic functions.
