Porphyrinoids as a platform of stable radicals
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.
Solution and on-surface synthesis of structurally defined graphene nanoribbons as a new family of semiconductors
Graphene nanoribbons (GNRs) with various structures and properties can be synthesized in solution or on surface.
Hierarchically porous carbons as supports for fuel cell electrocatalysts with atomically dispersed Fe–Nx moieties
Fe–Nx–C catalysts fabricated with hierarchically porous carbons instead of commercial carbon black demonstrate enhanced ORR performance under full-cell testing.
Martensitic organic crystals as soft actuators
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.
Two-photon-excited ultralong organic room temperature phosphorescence by dual-channel triplet harvesting
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.
Interplay of secondary and tertiary folding in abiotic foldamers
Helical secondary folds are stabilized within abiotic helix–turn–helix tertiary structures in organic solvents.
Gyroid structured aqua-sheets with sub-nanometer thickness enabling 3D fast proton relay conduction
We have succeeded in creating gyroid-nanostructured polymer films having a 3D continuous proton conduction pathway.
Upcycling aromatic polymers through C–H fluoroalkylation
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.
Triperyleno[3,3,3]propellane triimides: achieving a new generation of quasi-D3h symmetric nanostructures in organic electronics
A novel propellane rylene imide is synthesized. It serves as a versatile building block for quasi-D3h symmetric nanostructures.
Mapping binary copolymer property space with neural networks
We map the property space of binary copolymers to understand how copolymerisation can be used to tune the optoelectronic properties of polymers.
Targeting triple-negative breast cancer cells using Dengue virus-mimicking pH-responsive framboidal triblock copolymer vesicles
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.
Wave-shaped polycyclic hydrocarbons with controlled aromaticity
Herein, we describe an efficient synthetic strategy to control the aromaticity and optoelectronic properties of curved π-conjugated molecules.
A double helix of opposite charges to form channels with unique CO2 selectivity and dynamics
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.
Controllably realizing elastic/plastic bending based on a room-temperature phosphorescent waveguiding organic crystal
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 for the discovery of porous organic cages
An evolutionary algorithm is developed and used to search for shape persistent porous organic cages.
Facile room temperature synthesis of large graphene sheets from simple molecules
The simplest way to produce large graphene sheets starting from simple molecules (benzene or n-hexane) under ambient conditions (temperature and pressure).
Enhancement of triplet-sensitized upconversion in rigid polymers via singlet exciton sink approach
Quenching of emitter singlets by the sensitizer limits the efficiency of sensitized upconversion, unless an emissive exciton sink is employed.
Switchable gate-opening effect in metal–organic polyhedra assemblies through solution processing
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 for fragmentation-alkynylation cascades of cyclic oxime ethers
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.
Pyrene hydrogel for promoting direct bioelectrochemistry: ATP-independent electroenzymatic reduction of N2
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.
Spatially resolved acyl transfer on surface by organo-catalytic scanning probe nanolithography (o-cSPL)
Local and catalytic acyl transfer for multipatterning of surfaces.
Impact of helical organization on the photovoltaic properties of oligothiophene supramolecular polymers
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 for intracellular multi-color labelling in live cells
A palette of background-free tame fluorescent probes were designed and applied to intracellular multi-color labelling in live cells.
Ultrasensitive and specific fluorescence detection of a cancer biomarker via nanomolar binding to a guanidinium-modified calixarene
A well-designed macrocycle affords nanomolar binding to a cancer biomarker lysophosphatidic acid, showing potential application in the diagnosis of gynecologic cancers.
Injectable hyperbranched poly(β-amino ester) hydrogels with on-demand degradation profiles to match wound healing processes
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.
About this collection
In honour of our first Chemical Science symposium being held in September 2019 at our headquarters in Burlington House, London, we have put together a special collection of some of our favourite articles in this area, including a few by some of the speakers at the symposium.
