Cleavage of non-polar C(sp2)‒C(sp2) bonds in cycloparaphenylenes via electric field-catalyzed electrophilic aromatic substitution - Nature Communications
Abstract Electrophilic aromatic substitution (EAS) is one of the most fundamental reactions in organic chemistry. Using an oriented external electric field (OEEF) instead of traditional reagents to tune the EAS reactivity can offer an environmentally friendly method to synthesize aromatic compounds and hold the promise of broadening its scope.
Highly Efficient Photocatalytic Formic Acid Decomposition to Syngas under Visible Light using CdS Nanorods Integrated with Crystalline W2N3 Nanosheets
Highly Efficient Photocatalytic Formic Acid Decomposition to Syngas under Visible Light using CdS Nanorods Integrated with Crystalline W2N3 Nanosheets Taotao Wang, Muqing Chen, Jinbao Wu and Pingwu Du Abstract Syngas (H2/CO) production by photocatalytic formic acid decomposition is a promising method for solar energy conversion. Furthermore, syngas can be used as a fuel in internal combustion engines and can also be converted to other liquid fuels as well as high-value chemicals.
Selective Synthesis and (Chir)optical Properties of Binaphthyl-based Chiral Carbon Macrocycles
Selective Synthesis and (Chir)optical Properties of Binaphthyl-based Chiral Carbon Macrocycles Pengwei Fang, Muqing Chen, Xingyu Zhang and Pingwu Du Abstract Herein, we report the selective synthesis, characterization, and photophysical properties of two novel chiral carbon macrocycles. Non-planar (S)-2,2'-bis(methoxymethoxy)-1,1'-binaphthalene was introduced into the scaffold of oligo-paraphenylenes to achieve the chirality in these macrocycles.
An unexpected dual-emissive luminogen with tunable aggregation-induced emission and enhanced chiroptical property - Nature Communications
Abstract In the literature, organic materials with both aggregation-induced emission (AIE) and aggregation-caused quenching (ACQ) effects that can emit with multiple bands both in the solution and aggregated state are rarely reported. Herein we report a novel chiral dual-emissive bismacrocycle with tunable aggregation-induced emission colors.

Synthesis of a magnetic π-extended carbon nanosolenoid with Riemann surfaces - Nature Communications
Abstract Riemann surfaces are deformed versions of the complex plane in mathematics. Locally they look like patches of the complex plane, but globally, the topology may deviate from a plane. Nanostructured graphitic carbon materials resembling a Riemann surface with helicoid topology are predicted to have interesting electronic and photonic properties. However, fabrication of such processable and large π-extended nanographene systems has remained a major challenge.
Precise Membrane Separation of Nanoparticles Using a Microporous Polymer Containing Radially π-Conjugated Molecular Carbocycles
Precise Membrane Separation of Nanoparticles Using a Microporous Polymer Containing Radially π-Conjugated Molecular Carbocycles Pingwu Du, Shengda Wang, Qiang Huang, Jinyi Wang, Pingsen Huang and Pengwei Fang Abstract Aligned single-walled carbon nanotube membranes could be ideal candidates for nanoseparation and ion channels due to their uniform porous structures. However, it is a great challenge to construct a separation membrane with a regular arrangement of carbon nanotubes.
Highly Active Homogeneous Molecular Iron Catalysts for Direct Photocatalytic Conversion of Formic Acid to Syngas (CO+H2) at Room Temperature by Visible Light
Research Article Pingwu Du Corresponding Author E-mail address: dupingwu@ustc.edu.cn University of Science and Technology of China (USTC), Chemistry and Materials Science & Engineering, No.96, Jinzhai Road, 230026 Hefei, CHINA Search for more papers by this author Abstract The catalytic decomposition of formic acid to generate syngas (a mixture of H 2 and CO) is a highly valuable strategy for energy conversion.
Selective Synthesis of Conjugated Chiral Macrocycles as Sidewall Segments of (‐)/(+)‐(12,4) Carbon Nanotube with Strong Circularly Polarized Luminescence
Research Article PDF PDF Share Abstract Carbon nanotubes (CNTs) have unusual physical properties which are valuable for nanotechnology and electronics but the chemical synthesis of chirality‐ and diameter‐specified CNTs and π‐conjugated CNT segments is still a great challenge. Herein we report the selective synthesis, isolation, characterizations, and photophysical properties of two novel chiral conjugated macrocycles ([4]cyclo‐2,6‐anthracene, [4]CAn2,6) as (‐)/(+)‐(12,4) carbon nanotube segment.
Degradation Chemistry and Stabilization of Exfoliated Few-Layer Black Phosphorus in Water
Exfoliated black phosphorus (BP), as a monolayer or few-layer material, has attracted tremendous attention owing to its unique physical properties for applications ranging from optoelectronics to photocatalytic hydrogen production. Approaching intrinsic properties has been, however, challenged by chemical reactions and structure degradation of BP under ambient conditions.
