rigidity and inclusion behavior to trigonal C3-symmetric triphenol hosts H1–H4. Triphenol H1 is found to mimic the O–H···O hydrogen-bonded self-assembly of trimesic acid to yield porous honeycomb nets. It is found that 18-crown-6⊂H1 in turn binds guest molecules in the hexagonal voids to yield guest⊂guest⊂host multicomponent molecular crystals. The triphenol H2 and the homologous derivatives H3 and H4 are
通过甲基引入的空间使C 3对称的三酚三方体H1 - H4具有刚性和包容性。发现三酚H1模仿邻苯二酸的O-H ·· O氢键结合自组装产生多孔蜂窝网。据发现,18-冠6⊂ H1反过来结合客体分子在六角形的空隙,以产生多组guest⊂guest⊂host分子晶体。三酚H2和同源衍生物H3和H4还发现18-crown-6与18-crown-6和其他客体一起结晶产生多组分晶体,但在这些情况下,发现18-crown-6可作为间隔物。虽然H2的结构以无客体的形式确定,但三酚的一些包合物会使其自身形成晶体填料,这些填料会根据网络拓扑结构进行解密。对于H1 – Tol和H3 – C – B – Et观察到的网络是唯一的;在后者中,晶体堆积分析揭示了分子组成的模式,使人联想起硼烷环。
