Single-crystal X-ray diffraction analysis reveals that 1 exhibits a two-dimensional （2D） layer based on π-π stacking interactions between phen. Simultaneously, the adjacent 2D layers are assembled via π-π stacking interactions between phen and quinoline tings into a 3D supramolecular structure. The zero- dimensional structure of 2 is also further extended by π-π interactions to form a 2D supramolecular layer. Furthermore, these two compounds exhibit photoluminescence at room temperature in the solid state and their photocatalytic activities have been studied by degradation methylene blue.
