Table 1 Relaxation parameters of the neat solvents at 25 °C: static dielectric constant εs, infinite frequency permittivity ε∞, relaxation time τ, and the derived effective dipole moments μeff. Kinematic (ν) and dynamic (η) viscosities at 23.1 ± 0.2 °C as well as densities ρ of xFB at the indicated temperatures [T]
