摘要：

Carbon sandwich: When a pyrrole-containing surfactant is polymerized between layers of silica (see picture; pyrrole is red), subsequent carbonization and removal of the silica template yields large, pure, single-layer graphene sheets. The procedure, which employs mild conditions, is controllable and can be used to produce micrometer-sized graphene sheets on a gram scale. © 2009 Wiley-VCH Verlag GmbH & Co. KGaA.
