Jin, Xin published the artcilePinning-down molecules in self-assemblies with multiple weak hydrogen bonds of C-H···F and C-H···N, Application In Synthesis of 685517-67-3, the main research area is mol self assembly hydrogen bond.
Two-dimensional self-assemblies of four partially fluorinated mols., 1,4-bis(2,6-difluoropyridin-4-yl)benzene, 4,4′-bis(2,6-difluoropyridin-4-yl)-1,1′-biphenyl, 4,4′-bis(2,6-difluoropyridin-4-yl)-1,1′:4′,1”-terphenyl and 4,4′-bis(2,6-difluoropyridin-3-yl)-1,1′-biphenyl, involving weak intermol. C-H···F and C-H···N hydrogen bonds were systematically investigated on Au(111) with low-temperature scanning tunneling microscopy. The inter-mol. connecting modes and binding sites were closely related to the backbones of the building blocks, i.e., the mol. length determines its binding sites with neighboring mols. in the assemblies while the attaching positions of the N and F atoms dictate its approaching and docking angles. The exptl. results demonstrate that multiple weak hydrogen bonds such as C-H···F and C-H···N can be efficiently applied to tune the mol. orientations and the self-assembly structures accordingly.
