Mesostructured fullerene crystals through inverse polymeric micelle assembly

Mesostructured fullerene (C-60) film is synthesized using polymeric reverse micelles of poly(styrene-b-2-vinyl pyridine-b-ethylene oxide) (PS-b-PVP-b-PEO) triblock copolymer. Effective interaction between the electron donating pyridine units and electron accepting C-60 is the driving force to form composite micelles. Mesostructured C-60 with pore size of 20-25 nm shows highly crystallized walls in which the lattice fringes are coherently extended across several mesopores. (c) 2017 Elsevier B.V.
