Kagome-topology 2D covalent organic frameworks assembled from <i>D</i>_2h-symmetric and non-centrosymmetric <i>C</i>₂-symmetric blocks for photothermal imaging

Abstract

topology characterized by a favorable anti-parallel stacking arrangement, which results in a lower energy configuration. Notably, COF-DP, with its unique D-A-D structural motif and photosensitive properties, demonstrates a narrow band gap and excellent photothermal conversion capabilities, making it a promising material for photothermal imaging applications.
