[INORG-19]Ligand substitution of osmaanthracyne

Aromatic metallacycles of transition metals have caught attention for a long period of time. Members of the monocyclic six-membered aromatic metallacycle family has been well studied. Naturally, the chemistry of aromatic metallacycles with a more extended structure is of interest. Our group has recently reported the synthesis of an osmaanthracyne complex (1) with a tricyclic system. This study focuses on the derivatization of this compound by ligand substitution reactions.

[INORG-17] Understanding the diverse reactivity of pentaphenylborole toward epoxides

In this work, we report our systematic study on the diverse reactivity of pentaphenylborole toward different epoxides with the aid of DFT calculations. We have investigated how different substituents on epoxides influence the preference/competition of the three experimentally observed pathways, i.e. intramolecular proton transfer, direct ring expansion via insertion of one epoxide molecule, and ring expansion via insertion of two epoxide molecules. We also predict that when both Me and Ph substituents are present, the two pathways, intramolecular proton transfer and direct ring expansion, are highly competitive.

[INORG-15]Heterochiral self-discrimination-driven supramolecular self-assembly of decanuclear gold(I)-sulfido complexes into 2D nanostructures with chiral anions-tuned

Heterochiral self-discrimination between two chiral decanuclear gold(I) enantiomers gives rise to self-assembled 2D nanostructures. The introduction of chiral anions has been shown to tune the morphology of these 2D NCs from rhombic NCs to bilayer strip and quasi-hexagonal nanosheets. The current finding provides an important alternative towards the easy fabrication of regular geometric 2D nanostructures based on polynuclear gold(I) complexes.

[INORG-14]Concentration- and solvation-induced reversible structural transformation and assembly of polynuclear gold(I) sulfido complexes

Concentration-dependent reversible cluster-to-cluster transformation between a dodecanuclear gold(I) sulfido complex (LMe-Au12) and a hexanuclear gold(I) sulfido complex (LMe-Au6) has been observed. This represents the first example of the reversible transformation between two clusters simply by changing the concentration of the gold(I) sulfido complex under mild conditions. The occurrence of the interconversion has provided a system for the study and understanding of supramolecular transformations in polynuclear gold(I) systems under the application of external stimuli.

[INORG-12]Supramolecular assembly of bent dinuclear amphiphilic alkynylplatinum(II) terpyridine complexes: diverse nanostructures through subtle tuning of the mode of

A new class of bent amphiphilic alkynylplatinum(II) terpyridine complexes was found to adopt different modes of molecular stacking to give diverse nanostructures. In chlorinated solvents, the complexes aggregate in the presence of water droplets and assist in the formation of porous networks, while in DMSO solutions, they self-assemble to give fibrous nanostructures. This class of complexes serve as versatile building blocks to construct orderly packed molecular materials and functional materials in a well-controlled manner.

[INORG-11]Three-dimensional spirothienoquinoline-based small molecules for organic photovoltaic and organic resistive memory applications

A new spiro structure, namely spirothienoquinoline tBuSAF-Th, has been designed and utilized as a building block to construct functional materials for organic electronic applications. Both the photophysical and electrochemical properties of this class of spirothienoquinoline-based compounds can be fine-tuned by simple and judicious modifications on the molecular backbone. Further exploration of their applications in bulk heterojunction solar cells and organic resistive memory devices by employing this class of compounds as active materials have demonstrated their potentials in organic electronics.
