Abstract

We present here that in two-dimensional (2D) fullerene supramolecular liquid crystals (SLCs), the phase diagram and lamella thickness of SLCs and 2D crystals can be tuned by the flexible alkyl tail and spacer length, due to their different effects on enthalpy and entropy changes during SLC formation.
