Paper Abstract

It is shown that the excitation annihilation kinetics of a finite molecular assembly asymptotically approaches the steady state corresponding to the last excitation remaining in the system. The excitation decay kinetics after eliminating the steady state signal reveals the asymptotic dominance of the slowest annihilation mode. The corresponding annihilation time can be easily estimated from the experimental kinetic traces to give a measure of the system size. The annihilation time estimations for the light-harvesting complex LH2, C60 structures and a few poly(arylene vinylenes) are presented.
