This review surveys four types of stable porphyrinoid radical and covers their synthetic methods and properties. The remarkable radical-stabilizing abilities of porphyrinoid stem from their unique macrocyclic conjugated systems with high electronic and structural flexibilities.

Graphene nanoribbons (GNRs) with various structures and properties can be synthesized in solution or on surface.

Fe–N_x–C catalysts fabricated with hierarchically porous carbons instead of commercial carbon black demonstrate enhanced ORR performance under full-cell testing.

Being capable of rapid and complete structure switching, the martensitic phase transitions in molecular crystals are thought to hold a tremendous potential as thermally driven organic actuators.

Small energy gap boosts dual-channel triplet harvesting via TADF and UOP, which suppresses long-lived triplet concentration quenching. An infrared laser (808 nm) is able to induce persistent emission under ambient conditions.

Helical secondary folds are stabilized within abiotic helix–turn–helix tertiary structures in organic solvents.

We have succeeded in creating gyroid-nanostructured polymer films having a 3D continuous proton conduction pathway.

This work provides a platform C–H functionalization method that introduces fluoroalkyl groups onto commercial aromatic polymers and post-consumer plastic waste that improve their material properties.

A novel propellane rylene imide is synthesized. It serves as a versatile building block for quasi-D_3h symmetric nanostructures.

We map the property space of binary copolymers to understand how copolymerisation can be used to tune the optoelectronic properties of polymers.

Dengue fever-mimicking pH-responsive framboidal triblock copolymer vesicles enable delivery of a nucleic acid payload to the nuclei of triple-negative breast cancer cells.

Herein, we describe an efficient synthetic strategy to control the aromaticity and optoelectronic properties of curved π-conjugated molecules.

Electrostatic charges patterning along crystalline channels recognize CO₂ with high selectivity and promote its fast screwing dynamics through the crystal at one million steps per second, strongly reminiscent of trans-membrane transport in biological channels.

The room-temperature phosphorescent DBBZL crystals could exhibit reversible bending and irreversible bending based on one crystal. These flexible crystals exhibit good waveguiding property in straight state, elastic bending state and plastic bending state, demonstrating the application of flexibility.

An evolutionary algorithm is developed and used to search for shape persistent porous organic cages.

The simplest way to produce large graphene sheets starting from simple molecules (benzene or n-hexane) under ambient conditions (temperature and pressure).

Quenching of emitter singlets by the sensitizer limits the efficiency of sensitized upconversion, unless an emissive exciton sink is employed.

Assemblies of lantern-type metal–organic polyhedra are found to show gate-opening gas adsorption depending on how they are treated with solvents.

Fine-tuned organic photoredox catalysts are introduced for the metal-free alkynylation of alkylnitrile radicals generated via oxidative ring opening of cyclic alkylketone oxime ethers.

We demonstrate a novel hydrogel material to facilitate direct bioelectrochemistry of a wide range of redox proteins and enable ATP-independent electroenzymatic reduction of N₂ by nitrogenase.

Local and catalytic acyl transfer for multipatterning of surfaces.

Higher order structures of semiconducting supramolecular polymers have a huge impact on their BHJ-OPV device performance.

A palette of background-free tame fluorescent probes were designed and applied to intracellular multi-color labelling in live cells.

A well-designed macrocycle affords nanomolar binding to a cancer biomarker lysophosphatidic acid, showing potential application in the diagnosis of gynecologic cancers.

1A series of hyperbranched poly(β-amino ester) polymers have been synthesized via a Michael addition approach for the fabrication of hydrogels for wound healing.
