Single-crystal structure of two-dimensional organic framework based on donor-acceptor interactions with charge-transfer effect

Two charge-transfer single crystals induced by donor-acceptor interactions were obtained.The presence of different solvent molecules led to 1D(linear)or 2D self-assembly modes.More interestingly,the 2 D organic framework,a layer-by-layer 2D organic framework single crystal,showed a stronger charge-transfer effect than the 1D cocrystal.
