Synthesis of Metallophthalocyanine Covalent Organic Frameworks That Exhibit High Carrier Mobility and Photoconductivity

A light COF: Two-dimensional covalent organic frameworks of a nickel phthalocyanine have been synthesized. Owing to well-ordered stacking of the phthalocyanine units, the resulting 2D framework provides enhanced and broad light absorbance and facilitates charge transport. The material becomes highly photoconductive and is exceptionally sensitive to deep-red visible and near-infrared light.
