摘要
以1,5-萘二磺酸(1,5-H_2NDS)和三苯甲胺(TPMA)为建筑块、水和二氧六环(DO)混合溶液为溶剂,分别在室温和70℃下合成了2个超分子化合物2(HTPMA)+·(NDS)^(2-)·2DO·2H_2O(1)和(HTPMA)+·(H_3O)^+·(NDS)^(2-)·DO(2),并对其进行了单晶X-射线衍射、热重分析(TG)及荧光光谱(PL)分析。在化合物1中,[(SO_3)_2(NH_3)_2]簇通过N—H…O氢键与DO分子相互作用形成沿a方向的一维带状结构,相邻的带通过NDS^(2-)阴离子的萘环扩展为二维层,这些层进一步由水分子与HTPMA^+之间的C—H…O氢键连接形成三维超分子网络。化合物2中的[(S1O_3)_2(NH_3)_2]簇和[(S2O_3)_2(H_3O)_2]簇相互连接形成沿b方向的一维带状结构,这些带同样通过萘环扩展为二维层状结构。热重分析结果表明,化合物1和2分别于50℃和86℃开始失重。此外,2个化合物在390、392nm处均具有较强的室温固态荧光发射。
Two supramolecular complexes 2(HTPMA)^+·(NDS)^(2-)·2DO·2H_2O(1) and(HTPMA)^+·(H_3O)^+·(NDS)^(2-)·DO(2)are obtained from the reaction of triphenylmethylamine(TPMA)with naphthalene-1,5-disulfonic acid(1,5-H_2NDS)in the mixture of H_2O and dioxane(DO)at room temperature and 70 ℃,respectively,which have been characterized by singlecrystal X-ray diffraction,TG and PL.In the structure of complex 1,[(SO_3)_2(NH_3)_2]clusters interact with DO molecules through N—H…O hydrogen bonding interactions to form 1-D tape along a-axis.Adjacent tapes are extended into 2-D layers by naphthalene rings of the NDS^(2-)anions,which are then further linked into 3-D supramolecular network by the water molecules through C—H…O hydrogen bonding interactions.By contrast,the[(S1O_3)_2(NH_3)_2]and [(S2O_3)_2(H_3O)_2]clusters in complex 2 are joined by H_3O^+through O—H…O hydrogen bonding interactions to form 1-D tape along the b-axis.The 2-D layer is also extended by naphthalene rings of the NDS^(2-)anions.Thermogravimetric analyses indicate that complexes 1 and 2 begin to lose the solvents at 50℃and 86℃.Moreover,the two complexes exhibit luminescent emissions at 390 and 392nm at room temperature in the solid-state.
