  "abstract": "Bandgap engineering in covalent organic frameworks (COFs) is critical for their optoelectronic and photocatalytic applications, but it remains far less developed compared to linear p-conjugated polymers. Here, we demonstrate that permutation of π-conjugation pathway provides a general strategy to tune the electronic structure of covalent organic frameworks (COFs). An asymmetric benzotrithiophene ( A BTT) node enables a more efficient electron delocalization compared to its commonly used symmetric analogue ( S BTT), resulting in ∼0.05–0.2 eV band-gap contraction and improved charge-transport properties in corresponding COFs, with electrical conductivity up to 1.6×10 –1 S cm –1 in iodine-doped films.",
