2D, and 1D supramolecular structures through hydrogen bonds and π–π interactions. Structural analysis shows that co-crystals 1–3 are constructed into a hydrogen bond ring and chain with graph set notations R33(28), R22(26), C (8), and R66(38), through hydrogen bonds, respectively. Co-crystal 1 has obvious fluorescence properties due to its large conjugate plane. Through the study of the fluorescence
三种共晶化合物1–3 (NDI-A·芴) ( 1 ), (H 3 TIBTC·4,4'-bipy) ( 2 ), (H 3 DIBTC·4,4'-bipy) ( 3 ) (NDI-A = N , N '-di(4-pyridylacylamino)-1,4,5,8-萘二亚胺,H 3 TIBTC = 2,4,6-triiodo-1,3,5-苯三羧酸,H 3 DIBTC = 2,4-二碘-1,3,5-苯三甲酸,4,4'-bipy = 4,4'-联吡啶)首先通过水热法合成。结构分析表明共晶化合物1-3通过氢键和π-π相互作用具有3D、2D和1D超分子结构。结构分析表明共晶1-3分别通过氢键构造成具有图形集符号 R 3 3 (28)、R 2 2 (26)、C (8) 和 R 6 6 (38)的氢键环和链。共晶1由于其大的共轭面而具有明显的荧光特性。通过对NDI-A、芴和共晶1的荧光发射光谱及其固体
