[TOP] Nature Chemistry: Realizing a Brand-new Aromatic System, Metallapentalyne. (2013-06-23)

Aromaticity, one of the most fundamental concepts in organic chemistry, provides intrinsic stabilisation for cyclic compounds as a result of the delocalisation of π electrons. Currently, aromatic compounds (e.g., benzene, benzene derivatives, porphyrins, fullerenes, carbon nanotubes and graphene) have been applied in almost every field, including chemical engineering, biomedicine, materials science, energy science and environmental science.

Isolation, Reactivity, and Tunable Properties of a Strained Antiaromatic Osmacycle(2023-04-06)

We reported the first case of high-tensile and anti-aromatic carbon dragon compound, the metal bridgehead indene. The results were published online in the Journal of the American Chemical Society under the title "Isolation, Reactivity, and Tunable Properties of a Strained Antiaromatic Osmacycle." Am. Chem. Soc.

Synthesis and characterization of Craig-type antiaromatic species with [4n + 2] π electrons（2023-02-17）

We report the preparation method of the first Craig anti-aromatic species, and analyze the nature and driving force of antiaromatic species combined with theoretical calculation system. Thus, two centuries after the discovery of the first aromatic species (naphthalene), the puzzle of the π aromatic system was perfected . The results were published online in the Proceedings of the National Academy of Sciences under the title "Synthesis and Characterization of Craig-type Antiaromatic Species with [4n + 2] π Electrons"

Ring contraction of metallacyclobutadiene to metallacyclopropene driven by π- and σ-aromaticity relay（2022-12-14）

We have made another important advance in the field of "carbon dragon chemistry": we proposed a strategy based on π- and σ-aromatic relay drive, realizing the first metal heterocyclic butadiene to metal heterocyclic propylene ring shrinkage reaction. The results were published online in Nature Synthesis under the title "Ring Contraction of Metallacyclobutadiene to Metallacyclopropene Driven by π- and σ-Aromaticity Relay"

Selective Difunctionalization of Unactivated Aliphatic Alkenes Enabled by a Metal–Metallaaromatic Catalytic System（2022-02-09)

We describe a heterometallic [Os-Cu] complex with the characteristics of bimetallics, metallaaromatics, and pincer complexes. This complex serves as a highly effective catalyst for selective amino- and oxyselenation of unactivated alkenes. More than 80 examples including challenging substrates of unsymmetric aliphatic alkenes and amine-based nucleophiles in such reactions are provided.

Electrophilic aromatic substitution reactions of compounds with Craig-Möbius aromaticity(2021-09-22)

We directly employed metalla-aromatics to develop EAS reactions of Craig-Möbius aromatics with excellent efficiency and remarkable regioselectivity, and the reactions were quantified in computational studies to further rationalize the preferred sites of attack on the different aromatic rings.

Tuning an Electrode Work Function Using Organometallic Complexes in Inverted Perovskite Solar Cells(2021-04-27)

we use a series of synthesized (carbolong-derived) organometallic complexes as CILs to tune the electrode WF in inverted PSCs. Photovoltaic devices based on a Ag cathode, which was modified with these organometallic complexes, received a boosted PCE up to 21.29% and a remarkable fill factor that reached 83.52%, which are attributed to the dipole-enhanced carrier transport.

Nature Communications: Successive Modification of Polydentate Complexes Gives Access to Planar Carbon- and Nitrogen-based Ligands(2019-04-03)

Polydentate complexes containing combinations of nitrogen and carbon (N and C) ligating atoms are among the most fundamental and ubiquitous molecules in coordination chemistry, yet the formation of such complexes with planar high-coordinate N/C sites remains challenging. Herein, we demonstrate an efficient route to access related complexes with tetradentate CCCN and pentadentate CCCCN and NCCCN cores by successive modification of the coordinating atoms in complexes with a CCCC core.
