Adhesive organic network films with a holey microstructure: useful platforms for the engineering of flexible energy devices†
Pure silica zeolite (Silicalite-1) bricks with a 2D morphology were assembled on a slide glass and used as templates for the preparation of microstructured organic network films (MONFs) with a hollow space and holes by the Sonogashira coupling of tetrakis(4-ethynylphenyl)methane and 1,4-diiodobenzene and silica etching. The MONFs were adhesive to polyethylene terephthalate (PET) films due to their unique structural effects. Cu was loaded on the MONF/PET by electroless deposition. The Cu/MONF/PET showed excellent retention of conductivities in repeated severe bending.
