Emissive covalent organic frameworks (COFs) are a promising class of crystalline materials that have demonstrated applications for sensing and light-emitting diodes. However, white light emission from single COF has not been achieved yet as it requires multicomponent chromophores simultaneously emit blue, green, red light. In this work, we report the successful synthesis with efficient by utilizing tunable properties 2,1,3-benzothiadazole after incorporating different functional groups on its core structure, which results in formation three ligands, i.e., 4',4-(benzothiadiazole-4,7-diyl)-dibenzaldehyde (BTD), 4,4'-(benzoselenadiazole-4,7-diyl)-dibenzaldehyde (BSD), 4,4'-(naphtho[2,3-
