Stark Effects after Excited-State Interfacial Electron Transfer at Sensitized TiO2 Nanocrystallites

Journal of the American Chemical Society, 132(19), 6696–6709.

By: S. Ardo*, Y. Sun*, A. Staniszewski*, F. Castellano* & G. Meyer*

Contributors: J. Lakowicz*, H. Malak*, I. Gryczynski*, F. Castellano* & G. Meyer*

TL;DR: It is shown that the time-resolved anisotropy measurements can be extended to the submicrosecond timescale using metal-ligand complexes, which should enable measurement of DNA dynamics over a wide range of times (from 1 ns to several μs), which were previously inaccessible using time-resolution fluorescence.
