Abstract Covalent organic frameworks (COFs) have emerged as a compelling class of materials for active layers in memristors, yet the determinants their electrical properties and effective tuning strategies remain elusive. Herein, study unveils two novel pyrene‐based COFs (Py‐COFs)—the one‐dimensional (1D) H‐Py‐BT COF two‐dimensional (2D) Py‐BT COF—crafted with structural kinship divergent dimensionalities via tailored pyrene monomer connectivity. The effect dimensional disparities on memristive device performance image recognition precision is systematically investigated. Notably, 1D harnesses weak in‐plane interlayer hydrogen bonding interactions to enhance charge separation promote directional electron transport. This unique configuration enables devices fabricated (101 nm thick) deliver exceptional performance, evidenced by high ON/OFF current ratio (≈10 3.7 ) an accuracy 76%, outperforming those based 2D COF. These findings underscore pivotal role dimensionality molecular dictating functionality, offering valuable insights advancing COF‐based technologies.
