Fullerene crystals with bimodal pore architectures consisting of macropores and mesopores.

A new class of fullerene (C(60)) crystals with bimodal pore architectures consisting of macropores and mesopores was synthesized by using a liquid-liquid interfacial precipitation (LLIP) method involving an interface between isopropyl alcohol (IPA) and a saturated solution of C(60) in a mixture of benzene and carbon tetrachloride (CCl(4)). By varying the mixing fraction of CCl(4) in benzene, the porosity and electrochemically active surface area can be flexibly controlled.
