| Abstract
| - A series of thiol-substituted oligothiophenes were synthesized and used to functionalize the surface of CdSenanorods, via exchange with tetradecylphosphonic acid-capped particles. Attachment of the oligothiophenesto the CdSe nanorods results in little change to the electronic structure of the oligothiophenes as shown bythe similarities in the absorption spectra to the unbound oligothiophenes. The emission spectra of theoligothiophene-capped nanorods show that oligothiophene emission is quenched after attachment to the CdSesurface due to either an electron or energy transfer mechanism. The intensity of emission from the CdSenanorods differs depending on the number of oligothiophenes attached to the CdSe surface. A larger numberof bound thiols act as hole traps leading to quenching of the nanoparticle emission.
