    • The electrolyte-concentration dependence of vCT (in 10 3 cm-1) for these TICT molecules can be fitted to a biexponential function of the following form: vCT(c, a1 exp[-b1c, a2 exp[-b2c, with c as the electrolyte concentration moles per liter, In LiClO4 solutions of ethyl acetate the respective values of the fitting parameters for P4C, P5C and P6C are a 1, 2.67, 2.41, 2.46; a2, 19.37, 19.43, 20.15; b1, 4.17, 2.98, 3.41; and b2, 0.009, 0.007, 0.008. For acetonitrile containing LiClO4, the parameters are a1, 0.76, 0.71, 0.68; a2, 19.28, 19.39, 20.11; b1, 4.74, 5.09, 7.00; and b2, 0.02, 0.016, 0.024, with r2 ≃ 1 for all cases

    • Electrolyte-concentration-dependent net quantum yield of these TICT molecules in ethyl acetate can also be fitted nicely to a biexponential function of the following form: Φ(c, A1 exp[-B 1c, A2 exp[-B2c, with the following fitting parameters for P4C, P5C, and P6C sequentially, A1, 0.035, 0.026, 0.02; A2, 0.051, 0.012, 0.019; B1, 17.37, 6.54,6.03; and B2, 0.677, 0.118, 0.142. For acetonitrile containing LiClO4, the fitting parameters are A1, 0.005, 0.004, 0.008; A2, 0.025, 0.019, 0.011; B1, 15.75, 14.47, 11.92; and B2= 0.618, 0.455, 0.348, with r2 ≃ 1 for all cases
