Special Issue Information

Dear Colleagues,

Organic optoelectronic materials play an irreplaceable role in many research fields, such as organic solar cells, organic photodetectors, organic light-emitting diode, photo/electrocatalysis and so on. Developing novel materials is the key issue to improve device performance and commercial progress. Organometallic materials hold great potential with the advantages of both organic and metallic materials. Organic segments provide wide space to adjust the molecular energy levels and bandgap, as well as solubility, crystallinity, and flexibility. Metallic segments involving cheap metal or heavy metal facilitate the improvement in molecular stability, molecular packing, the yield of triplet excitons and catalytic centers. Therefore, the research on highly efficient organometallic materials and their optoelectronic application would attract considerable attention around the world.

This Special Issue aims to cover recent development and trends of novel organometallic materials and their optoelectronic application. We seek full research articles, short communications, and reviews related, but not limited, to the topics listed below:

  • Design of novel metal complex;
  • Design of metallated photovoltaic small molecules and polymers;
  • Design of metallated catalysis materials;
  • Organic photovoltaics;
  • Non-fullerene organic solar cells;
  • Thick-film solar cell based on triplet materials;
  • Organic photodetectors;
  • Phosphorescent organic light-emitting diode;
  • Dynamic process of triplet exciton in optoelectronic device.

We look forward to receiving your contributions.

Tailoring the morphologies and optical properties of the 2D and hierarchical nanostructures self-assembled by the π-conjugated molecules is both interesting and challenging. Herein, a series of 2D ribbon-like nanostructures with single or multiple H-aggregated perylene bisimides (PBI) monolayer and hierarchical nanostructures (including straw-like, dumbbell-shaped, and rod-like nanostructures) are fabricated by solution self-assembly of three chiral alanine-decorated PBI. The influence of the solvent’s dissolving capacity, the chirality of alanine, and the preparation methods on the morphologies and optical properties of the nanostructures were extensively studied. It was observed that the hierarchical nanostructures are formed by the reorganization of the 2D ribbon-like nanostructures. The size of the 2D ribbon-like nanostructures and the amount of the hierarchical nanostructures increase with the decrease in the solvent’s dissolving capacity. The small chiral alanine moiety is unable to induce chirality in the nanostructures, owing to its low steric hindrance and the dominant strong π-π stacking interaction of the PBI skeleton. A weaker π-π stacking interaction and better H-aggregated arrangement of the PBI skeleton could reduce the low-wavelength fluorescence intensity. The process of heating, cooling, and aging promotes the formation of H-aggregation in the PBI skeleton. The region of spectral overlap of the PBI solutions increases with the decrease in the dissolving capacity of the solvent and the steric hindrance of the chiral alanine. This study supplies a view to tailor the morphologies and optical properties of the nanostructures, which could be used as sensors and photocatalysts. Full article

Carbon dioxide (CO2) is a non-toxic, abundant and recoverable source of carbon monoxide. Despite its thermodynamically stable and kinetically inert nature, research on CO2 utilisation is ongoing. CO2-based aryne reactions, crucial for synthesising ortho-substituted benzoic acids and their cyclisation products, have garnered significant attention, and multi-component reactions (MCRs) involving CO2, aryne and nucleophilic reagents have been extensively studied. This review highlights recent advancements in CO2 capture reactions utilising phenylalkyne reactive intermediates. Mechanistic insights into these reactions are provided together with prospects for further development in this field. Full article
