Abstract
(Figure Presented) Stopover at G base: The efficiency of photoinduced charge separation between donor and acceptor chromophores separated by a polyadenine sequence containing a single guanine (G) is sensitive to the location of G and the total length of the polypurine sequence. Quantum yields provide support for a stepwise mechanism in which G serves as a temporary resting place in the overall process (Sa: stilbenedicarboxamide electron acceptor, Sd: stilbenediether electron donor).
