Rational molecular design for multicomponent guest inclusion in the solid state: differential binding of small and large aromatic guests
نویسندگان
چکیده
Tetraarylpyrene H that typifies a host system with three distinct domains for guest inclusion in the solid state is found to include different aromatic guests in the lattice and crystallize as a multicomponent molecular crystal. It is found to exhibit site-selective inclusion of the guests in that the large-sized guests such as biphenyl, anthracene, [2.2]paracyclophane, fluorene and pyrene are included selectively in the trough region, whereas small-sized benzene guest is bound in concave and/or basin regions. These results are of particular importance from the point of view of creating multicomponent molecular crystals based on rational design of the host structure.

Tetraarylpyrenes H1-H4 that typify molecular systems with orthogonal planes and lack hydrogen bonding functional groups were designed as new host systems with three distinct domains for guest inclusion. In particular, H2 and H4 hosts are found to include a variety of guest molecules. We have determined 42 crystal structures overall (i) to establish the importance of skeletal features of the hos...

Guest molecules in nonspherical cages of inclusion compounds can possess non-uniform spatial distributions and motion. This can lead to anisotropic lineshapes in the solid-state NMR spectra of the guest species. In this work, we use our previously developed molecular dynamics-based methodology to calculate the lineshape anisotropy of guest CO species in cages of the structure I (sI) clathrate h...

The C-ethyl-2-methylresorcinarene (1) forms 1:1 in-cavity complexes with aromatic N,N'-dioxides, only if each of the aromatic rings has an N-O group. The structurally different C-shaped 2,2'-bipyridine N,N'-dioxide (2,2'-BiPyNO) and the linear rod-shaped 4,4'-bipyridine N,N'-dioxide (4,4'-BiPyNO) both form 1:1 in-cavity complexes with the host resorcinarene in C4v crown and C2v conformations, r...

Three aromatic oligoamides have been prepared that have alternating 1,6-diaminopyridine and 1,6-pyridinedicarboxylic acid units at the center of the sequence and two 8-amino-2-quinolinecarboxylic acid units at each extremity. The three oligomers differ in the number--3, 5, or 7-of pyridine units in the sequence. They were designed to adopt helically folded conformations in solution and in the s...
