Single-Junction Organic Solar Cells with 19.17% Efficiency Enabled by Introducing One Asymmetric Guest Acceptor

Rui Sun et al.

Summary: The ternary strategy is an effective approach to achieve high-efficiency OSCs, but the nonradiative voltage loss limits further efficiency improvements. By incorporating an asymmetric guest acceptor BTP-2F2Cl, the OSCs show improved photoluminescence quantum yield, exciton diffusion length, and absorption spectrum, leading to enhanced power conversion efficiency.

Naphthobispyrazine Bisimide: A Strong Acceptor Unit for Conjugated Polymers Enabling Highly Coplanar Backbone, Short π - π Stacking, and High Electron Transport

Tsubasa Mikie et al.

Summary: This study developed and synthesized a novel acceptor unit for conjugated polymers. The resulting polymer showed significantly improved electron and hole mobilities compared to its predecessor, likely due to the highly coplanar and rigid backbone. Furthermore, the incorporation of fluorine atoms as conformation-directing groups resulted in higher solubility and regular backbone structure for the polymer.

Hydrogen-Bond-Promoted Planar Conformation, Crystallinity, and Charge Transport in Semiconducting Diazaisoindigo Derivatives

Anthony U. Mu et al.

Summary: This study focuses on using intramolecular noncovalent bonds to control the conformation and electronic properties of pi-conjugated molecules in the solid-state. The formation of intramolecular hydrogen bonds stabilizes the coplanar molecular conformation and enhances the thermal stability. Thermal annealing of thin films with these hydrogen bonds results in high crystallinity and orientation, leading to improved hole mobilities in field-effect transistor devices.

Reconsidering the Roles of Noncovalent Intramolecular Locks in π-Conjugated Molecules

Chamikara Karunasena et al.

Summary: This study investigates how variations in molecular design and processing chemistry influence the structure, dynamics, and aggregation tendencies of donor-acceptor oligomers in solution using quantum-chemical calculations and molecular dynamics simulations. The results reveal preferential rotational isomer populations based on oligomer chemistry, solvent environment, and oligomer concentration. Questions are raised regarding the current emphasis on noncovalent intramolecular interactions in the design of OSC building blocks.

Synthesis, characterization, and their field-effect properties of azaisoindigo-based conjugated polymers with versatile alkoxycarbonyl substituents

Yankai Zhou et al.

Summary: This study introduced versatile alkoxycarbonyl substituents onto the azaisoindigo-based polymeric pi-skeleton, leading to the synthesis of two novel polymers. Experimental results showed that alkoxycarbonyl substituents can effectively modulate the properties of conjugated polymers, enhancing solubility and optimizing molecular packing. All field-effect transistors based on these polymers exhibited ambipolar carrier transport characteristics, indicating the potential of alkoxycarbonyl substituents in fine-tuning the semiconducting properties of conjugated polymers.

A Molecular Replication Process Drives Supramolecular Polymerization

Yuanning Feng et al.

Summary: This study focuses on the design of a hydrogen-bonded polymer using a bifunctional monomer with self-replicating templates, which allows for autocatalytic polymer formation and high diastereoselectivity in the template-directed reaction. The high binding affinity between the replicating templates in solution enables polymerization and the assembly of the polymeric material has been characterized using various techniques. This approach proves to be a viable method for constructing supramolecular polymers and can be expanded to incorporate additional functionalities in the rigid spacer between replicating templates.
