报告摘要:

 

Advanced self-assembly strategies enable the targeted synthesis of supramolecular systems and materials with increasing structural and functional complexity. We react bis-monodentate ligands with transition metal cations to coordination compounds showing a broad range of topologies. To combine different functionalities in the same structure, we develop non- statistical assembly strategies based on “shape complementary assembly” (SCA), “coordination sphere engineering” (CSE) and “adjacent backbone interactions” (ABI).1

With a focus on multi-chromophore systems,2 we investigate the suitability of modular assemblies for light-induced charge separation, vectorial excitation transport and as potential photo-redox catalysts. By combining chiral with emissive ligands, heteroleptic cages showing guest-modulated circularly polarized luminescence (CPL) were obtained.3 We further introduce stimuli-responsive behavior in photochromic cages4 allowing to control guest affinity5 and established a light-fueled dissipative system.6 Cages capable of fullerene encapsulation7 give rise to confinement-controlled reactivity, such as long-term C60 radical anion stabilization.8 Recently, we mastered the non-statistical and robust assembly of dinuclear Pd(II) cages containing four chemically different ligands [Pd2ABCD].9 Such structures can also be obtained with kinetically more inert Co(III)salphen complexes.10 The collected results now set the stage for creating ‘complex systems’ behaviour by following the stimuli-responsive population and evolution of co-existing species in mixtures.11 In this direction, we study multi-step cage interconversions, guest-binding/release cascades and propagation of chiral information.

报告人简介:

 Guido H. Clever studied chemistry in Heidelberg and obtained his PhD in 2006 from LMU Munich. He then joined the lab of Mitsuhiko Shionoya at the University of Tokyo as an Alexander-von-Humboldt/JSPS postdoc and later Assistant Professor. In 2010 he became Junior Professor at Georg-August University Göttingen, where he climbed on a W2 professorship in 2013. In 2015, he became Full Professor at TU Dortmund University, holding the chair of Bioinorganic Chemistry. He obtained the ADUC Young Investigator Award (German Chemical Society), the Dozenten Award of the Fonds of the German Chemical Industry and an ERC Consolidator grant of the European Union. He is board member of DFG Cluster of Excellence RESOLV EXC2033 and Graduate School “Confinement-controlled chemistry” GRK2376. He serves as vice dean of the department of chemistry. His research interests include the development of non-statistical assembly protocols for low-symmetry metallo-supramolecular cages and the integration of chromophores, e.g. donor/acceptor combinations and light- switchable units. These find application in selective guest binding, chiroptical sensing, light- driven charge separation, cage-confined reactivity and systems chemistry. Furthermore, the Clever Lab studies transition metal-binding DNA G-quadruplexes to serve as a new type of EPR spin labels, enantioselective catalysts and stimuli-responsive protein binders with biomedical relevance.
