On-surface isostructural transformation from a hydrogen-bonded network to a coordination network for tuning the pore size and guest recognition

Abstract

Rational manipulation of supramolecular structures on surface is of great importance and challenge. We show that imidazole-based hydrogen-bonded networks on metal surface can transform to isostructural coordination network for facile...

Flow-induced-crystallization: tailoring host–guest supramolecular co-assemblies at the liquid–solid interface

“…According to the data, the five kinds of pores appear with similar energy from a theoretical viewpoint, consistent with STM investigations where diverse packing occurs. 26,27 The adsorption energies of C 60 inserted into the A–E pores were calculated to be −186.5, −181.1, −190.2, −153.7, and −152.0 kJ mol −1 , respectively (Fig. 2a, Table S2† in the ESI†).…”

Coordination-bond-directed synthesis of hydrogen-bonded organic frameworks from metal–organic frameworks as templates

“…For example, Zhang and co-workers have reported an isostructural transformation from a hydrogen-bonded network to a MOF on Au(111)/Ag(111) surfaces by replacing the weak N–H⋯N hydrogen bonds with stronger Ag–N coordination bonds. 33 But the reverse process ( i.e. replacement of coordination bonds by hydrogen bonds) has never been reported to the best of our knowledge.…”

Coronene guest molecule selectivity in host templates formed by hydrogen bonding and van der Waals forces at liquid/solid interfaces

“…11,12 In general, two-dimensional (2D) supramolecular porous networks are used as host templates to identify guest molecules and form orderly multi-component nanopatterns. 13,14 The host-guest recognition mainly depends on the size matching effect between the nanocavities of the template and guest molecules, [15][16][17] and the host-guest interactions. 18,19 Conjugated macrocycle self-assembled monolayers are suitable for adsorbing fullerenes as guests to form donor-acceptor (D-A) complexes.…”
