a Schematic illustration of Ni-BAND synthesis, showing the dissolution of the precursor ([Ni(bpy)(H2O)2(NO3)2]) in DMF (center), yielding crystals (top right) and films or gels (bottom right). b Photograph of as-synthesized Ni-BAND crystals. The scale bar denotes 5โmm. c Scanning electron microscope image of Ni-BAND crystals. The scale bar denotes 200โยตm. d Photograph of Ni-BAND films prepared on a SiO2(300โnm)/Si substrate (1.5โcmโรโ1.5โcm). e Photograph of Ni-BAND gel (2โcmโรโ2โcm) prepared on a glass substrate.
