Phthalocyanine covalent organic frameworks with different central metals are synthesized, and the AA-stacking structure of the 2D polymer sheets results in periodic phthalocyanine π-columns. The central metals control the π-electronic functions, including the improvement of light absorbance, the ease of carrier transport, and the photocurrent gain.
