This talk focuses on aromatic acceptor ligands for triplet-fusion based photon upconversion, where orbital overlap between the QD donor and molecular acceptor is critical for efficient energy transduction. In the past 7 years, we have learnt a great deal about how the electronic interactions between chalcogenide nanocrystals and aceneconjugated molecules affect the photon upconversionquantum yield. We apply the lessons learnt to extending photon upconversionto silicon nanocrystal light absorbers, addressing synthetic and self-assembly challenges with invaluable insight from time-resolved spectroscopy.
