Abstract: Bern Kohler opened discussion of the paper by Mike Jones: What about charge transfer as a possible explanation for the emission quenching you observe with the cadmium telluride quantum dots?Mike Jones answered: So far the data we have are consistent with a FRET mechanism, but we cannot rule out the involvement of charge transfer states.Professor Rienk van Grondelle has suggested we use Stark spectroscopy to explore this possibility.Anthony Watts asked: Do the quantum dots (QDs) cause any spectral shi in your engineered photoproteins, as seen with QD coupling to bacteriorhodopsin?Mike Jones replied: No, we haven't seen any inuence of these QDs on the absorbance spectra of the various wild type and mutant RCs and RCLH1 complexes we have attached to them. Richard Cogdell said: We see the quenching of the QD, but do you see the arrival of the energy at the reaction centre?Mike Jones replied: Yes.We see enhanced P photobleaching in the presence of QDs and we see enhanced emission from a mutant RC that is engineered to lack the primary electron donor.Anthony Watts asked: How do you know you've got that asymmetrical arrangement shown in your solar cell gure?Could controlling orientation be worth investigating?
