Steric hindrance to the solvation of melamines and consequences for non-covalent synthesis.

Steric hindrance to solvation disfavors structures like 1 synanti in which the melamine exposes to the solvent faces, such as tBu-H, for whom binding to the ring nitrogen is hindered but not blocked; steric hindrance to solvation lowers the barriers to rotation in solvents which bind the triazine nitrogens, therefore these solvents display the fastest rates for assembling/disassembling processes.
