2′-diol/isoquinoline (BINOL/ISOQUN) adducts were successfully synthesized. X-ray single crystals of BINOL/QUN and BINOL/ISOQUN were grown and analysed. The crystal packing of the molecules in both adducts confirmed that they are held in aggregates by strong hydrogen bonds (O2–H2⋯O3), (O3–H3⋯N1), (O2–H2⋯O1), (O1–H1⋯N1), (O2–H2⋯O1) and weak hydrogen C–H⋯π bonds. The patterns of the hydrogen bonding network as well
成功合成了1,1'-联萘-2,2'-二醇/喹啉(BINOL / QUN)和1,1'-联萘-2,2'-二醇/异喹啉(BINOL / ISOQUN)加合物。生长并分析了BINOL / QUN和BINOL / ISOQUN的X射线单晶。两种加合物中分子的晶体堆积证实它们通过强氢键(O2-H2⋯O3),(O3-H3⋯N1),(O2-H2⋯O1),(O1-H1⋯N1)保持聚集),(O2-H2⋯O1)和弱氢C-H⋯π键。氢键网络的图案以及BINOL的构型有助于形成截留喹啉和异喹啉的空隙的形状。用于研究BINOL / QUN和BINOL / ISOQUN的电子性质的分子模型表明,加合物的HOMO位置位于1,1'-联萘-2,2'-二醇(BINOL)周围,而LUMO则位于异喹啉和喹啉上。从等温滴定热法(ITC)获得的热力学参数显示,与喹啉/ BINOL相比,异喹啉/ BINOL的相互作用更强。将6-乙烯基-1
