摘　　要：Three porous nanocarbons,1–3 that comprise pyrene,corannulene,and coronene cores encircled by cyclo-meta-phenylene(CMP)interconnections,have been synthesized and characterized.The interconnected CMPs caused different curvatures of the cores and imparted high solubility,large bathochromic shift,strong fluorescence,and low reduction potential to the systems.In solution,these porous nanocarbons existed as a complex mixture of dynamic processes that certainly influenced one another within any single molecule,leading to a set of rather simple proton nuclear magnetic resonance(^(1)H NMR)spectra.Single crystal X-ray diffraction and computational minimum energy analysis revealed the boatand saddle-like conformations of 1–3 in the solid state,significantly deviating from their conformations on the Au(111)surface.Furthermore,both 1 and 2 could form 2:1 complexes with C_(60),accompanied by adaptive geometry changes.In addition,1 served as a sky-blue emitter for an organic light-emitting diode(OLED).This work gives access and insights into a model system consisting of porous nanocarbons with intriguing supramolecular and optoelectronic properties.
