[交流] 超分子分形化学

The three-dimensional branched architecture of a dendrimer consists of three topologically
distinct regions: multivalent surface, branching repeat and encapsulated core. This paper
discusses the use of dendritic architectures for supramolecular chemistry and, in particular,
focuses on the unique ability of the branched shell to affect molecular recognition processes
in these three regions. The multivalent nature of the fractal dendrimer surface allows
the recognition of multiple guests with maximum efficiency and accessibility. Such multivalent
recognition has been used both to enhance binding strengths for weak molecular
recognition processes, and also to endow the receptor with much improved guest sensing
properties.
With the site of recognition in the branched repeat unit, dendritic hosts can exhibit not
only high guest uptake, but also interesting cooperative binding effects.Meanwhile, recognition
sites buried at the core experience the unique microenvironment generated by the dendritic
branching. This microenvironment can generate new modes of binding and hence novel
guest selectivities. As a consequence, such host molecules can mimic aspects of biological
behaviour, particularly that of enzymes.Well-defined molecular recognition events with dendritic
molecules also provide an entry into more highly organised supramolecular constructions
and assemblies. This paper provides a survey of dendritic molecular recognition processes
and, in particular,highlights the different ways in which the branched shell can actively
control the binding event.
Keywords: Dendrimer,Supramolecular chemistry,Molecular recognition,Self-assembly,Microenvironment.
