A hybrid system comprising semiconductor quantum dots (QDs) ligated with photochromic molecules has been synthesized and used to study the photomodulation of QD luminescence. The system has been constructed in such a way that the excited-state energies of the QDs and the molecules match but only for one of the conformations of the chromophore, thus […]
