Radiationless Transitions of G4 Wires and dGMP

摘要: Steady-state and time-resolved emission techniques were employed to study the nonradiative process of deoxygunaosine monophosphate (dGMP) novel uniform continuous G4 wires containing hundreds stacked tetrads. We found that emissions both dGMP decay nonexponentialy. At room temperature, short-time is about 10 ps. low temperatures in ice, fluorescence quantum yields increase as temperature decreases. For wires, yield increases from 10−3 at 0.03 liquid-nitrogen temperatures. The asymptotic long-time lifetime-corrected obeys a power law. all temperatures, average time longer than dGMP. successfully used an inhomogeneous model fit experimental results.
