$V_{\text{tr}},$ $V_{\text{tr}}^{\left(\text{be}\right)},$ and $V_{\text{tr}}^{\left(\text{dae}\right)}$ for the polynorbornyl bridged model compounds with n = 1, 2 (see Fig. 2C for the molecular structures) with parallel D, A C=C bond fragments

Number of bridge units	$V_{\text{tr}},$ eV	$V_{\text{tr}}^{\left(\text{be}\right)},$ eV	$V_{\text{tr}}^{\left(\text{dae}\right)},$ eV
n = 1	$1.13\times {10}^{-1}$	$5.89\times {10}^{-2}$	$4.36\times {10}^{-2}$
n = 2	$2.39\times {10}^{-2}$	$2.01\times {10}^{-2}$	$2.70\times {10}^{-3}$

For these computations the energy gaps were lowered compared to their values in Table S3 (main text).
