Lay Summary (English)

Lead
The project is concerned with the design and construction of infinite structures and finite molecular structures that can be (i) used to trap and release small guest molecules and/or (ii) be photo-responsive. The project lasts over a two year period and also has the primary function of competing the training and chemical education of a doctoral student.

Abstract

The project is a continuation of a previous SNF funded project and focuses on synthesis, structural characterization and photophysical properties of coordination metallomacrocycles, polymers and networks in which metal ions form the nodes and derivatives of 4,2':6',4''-terpyridine are the linkers. The latter are functionalized with photoactive groups (e.g. biphenyl, anthracene, naphthalene). We will explore the colour-tuning of the photoluminescence by choice of ligand. From a structural standpoint, we aim to investigate: (i) structural control of coordination polymer assemblies using back-to-back 4,2':6',4"-terpyridines; (ii) structural modification induced by phenyl-perfluorophenyl p-stacking interactions; (iii) functionalized metallomacrocycles tailored to host p-organic guests in nanotube assemblies. By functionalizing 4,2':6',4"-tpy with photoactive domains, the emissive properties of the free ligands can be readily varied and subsequent binding of metal ions diversifies the photophysical properties. Zinc-containing hexacyclic arrays [Zn6X2(L)6], assembled using functionalized 4,2':6',4"-tpy and zinc(II) halides, are an exciting new family of conformationally flexible molecules. We will develop the host-guest chemistry of [Zn6X2(L)6] hexacycles in order to better understand their solution and solid state properties. Structure-property relationships will be developed and fed back iteratively into ligand design.
