Comparison of experimental and theoretical rotational diffusion constants of TOPO-NRs in toluene.

NRs FCS (105 s−1) HS (105 s−1) HS (105 s−1) w/TOPO TT (105 s−1) TT (105 s−1) w/TOPO B (105 s−1) B (105 s−1) w/TOPO Polarization Factor (R)
5×13 nm 6.5±1.1 33.30 18.24 18.50 9.84 NA NA 0.80
5×25 nm 2.2±0.1 7.63 5.17 4.79 3.11 4.31 2.70 1.00
5×32 nm 1.3±0.2 4.13 2.92 2.71 1.87 2.44 1.67 0.99

HS: hydrodynamic Stick theory; TT: Tirado and Garcia de la Torre theory; B: Broersma theory. NA: not applicable. It is assumed that TOPO adds 1nm to all sides of NRs.
