摘要	Two-photon absorption (2PA) materials are useful in optical devices as well as biomedical imaging and treatment. Molecular chromophores are advantageous in tuning the 2PA properties by different functional groups; however, it is challenging to precisely control the spatial arrangement of the chromophores and their underlying molecular dipoles. In this work, we present the linking of molecular chromophores to form COF crystals as a new way to achieve high 2PA absorption efficiency. The breakthroughs in both crystallization and structure characterizations made it possible to study the correlation between structural features of COFs and the 2PA property, valuable for the design of molecule-based 2PA materials. The critical factors are: (1) collective alignment of chromophores; (2) serrated packing between two-dimensional layers; (3) size of crystal domains; and (4) types of functional groups. The first and second points are unique merits from COFs and also the key to their high 2PA performance. © 2020 Elsevier Inc.
