Quantum dot (QD) semiconductor nanocrystals offer unique electronic, magnetic, and optical properties, that can be used in advanced materials applications including optoelectronics, catalysis, sensing, and quantum computing. Tailoring of quantum dot surface coatings allows for control of self-assembly and facile inclusion into various host matrices. Querner and colleges have provided a novel synthetic route to graft aniline tetramer units onto quantum dots via a disulfide bridge. A key goal of our work has been the optimization of this synthesis for inclusion of functionalized QDs within Laponite/polyaniline nanoscaffolds. Uv/visible and fluorescence spectroscopy were used to study frequency resonance energy transfer within our QD/Iinker/tetramer/Laponite system. Our studies illustrate that Laponite affords an ideal host framework for realization of QD based light emitting diodes and photovoltaics.
