𝑟 " Where F is the force, q is the charge of the ions, k is a constant, and r represents the distance between the cation and anion. As the electrostatic force is inversely proportional to r 2 , if r is larger, the corresponding electrostatic force will vastly decrease. Therefore, the use of bulky cations and anions will generally reduce the electrostatic interactions between the ionic species, often resulting in lower melting points. Second, we previously found this anion to be cavity-excluded in a type III based porous liquid consisting of porous organic cage microparticles, and therefore hypothesised that it would also be cavity-excluded from the targeted system here.
