Abstract: Nonequilibrium self-assembly of molecules holds a huge prospect as a tool for obtaining new-generation materials for future applications. Crystallization of neutral molecules within a supramolecular gel matrix is one example in which two nonequilibrium processes occur orthogonal to each other. On the other hand, electronically interacting donor-acceptor two-component systems are expected to form phase-miscible hybrid systems. Contrary to the expectation, we report the behavior of a p-gel, derived from oligo(p-phenylenevinylene), OPVA, as a scaffold for the phase separation and crystallization of fullerene (C60) to supramolecular rods with increased transient photoconductivity (fƩmmax = 2.4 × 10−4 cm2 V−1 s−1). The C60 supramolecular rods in the p-gel medium exhibited high photocurrent in comparison to C60 loaded in a non–p-gel medium. This finding provides an opportunity for largescale preparation of micrometer-sized photoconducting rods of fullerenes for device application
