^*Obtained from electron transmission studies when the capturing probability is given by (I_Au – I_nG)/I_Au, when I_Au is the energy-integrated photoelectron signal obtained for bare gold and I_nG is the integrated electron transmission signal (Fig. 3) obtained for the nG oligomer

^†The calculated capturing probability is based on the TPPE signal (Fig. 5) and is normalized relative to the signal obtained for 1G^3′ oligomer
