Layered bulk crystals are amenable to exfoliation to yield 2D nanosheets through isolation and intercalation processes, which could be further converted to 1D nanoscale structures. The latter inherit gross morphol. and phys. properties associated with the precursor structures. Herein, we report three purine-based crystal structures 1, 2, and 3, where 3 is obtained by a single-crystal-to-single-crystal transformation from 2 and is a conformational polymorph of 1. Next, we describe the sonication-assisted liquid exfoliation of 1, a CdII-purine coordination framework, into nanosheets and nanofibers in a solvent-dependent process. The exfoliation was carefully studied at low temperatures to ascertain this unique conversion. This work also features the determination of the Young’s modulus and surface potential of the bioinspired CdII-based nanostructures by using amplitude modulation-frequency modulation at. force microscopy and Kelvin probe force microscopy, resp., revealing their interesting elastic and capacitive properties for their possible use in electronics and energy devices. Electron impedance spectroscopy measurements further established a higher value of capacitance for the exfoliated CdII framework as compared to the ligand alone. In the part of experimental materials, we found many familiar compounds, such as 2-(Bromomethyl)pyridine hydrobromide(cas: 31106-82-8Name: 2-(Bromomethyl)pyridine hydrobromide)
2-(Bromomethyl)pyridine hydrobromide(cas: 31106-82-8) belongs to pyridine. Pyridine is very deactivated towards electrophilic substitution with respect to benzene. For this reason classical formylation, using methods such as the Gattermann or Vilsmeier reactions, are not generally successful. Name: 2-(Bromomethyl)pyridine hydrobromide
