Abstract Visualized sensing through fluorescence signals is a powerful method for chemical and physical detection. However, the utilization of fluorescent molecular probes still suffers from lack precise signal self-calibration in practical use. Here we show that thermally activated delayed can be simultaneously produced at single-molecular level. The serves as with its wavelength lifetime both altered correlating to polarity, whereas always remains unchanged an internal reference. Upon...
This study seeks to explore whether electrochemical reduction of CO2 (using current US average and future low carbon electricity) will become a viable route for the reuse producing synthetic fuel. paper presents results technical economic analysis conducted pathway that converts released from fossil fuel-burning power plants diesel fuel via CO Fischer–Tropsch process. Currently achievable performance levels electrolyzers process were used compute key metrics, including (i) cost fuel, (ii)...
Here we report a chemical strategy that uses rigid molecules to straightforwardly construct amphiphilic carbon dots (ACDs) with high luminescence quantum yields (QYs).
The exploration of emission pathways from high-excited states in organic luminogens has recently become prosperous owing to improved possibilities study so-called anti-Kasha's rule with the potential improving luminescent quantum efficiency. However, pathway switching among different rarely been addressed through external control. We here present a rational design and synthesis novel azulene-based emitter achieve responsive control its emissive switching. initially gives rise an S3-to-S0...
Abstract The fact that the lifetime of photoluminescence is often difficult to access because weakness emission signals, seriously limits possibility gain local bioimaging information in time‐resolved luminescence probing. We aim provide a solution this problem by creating general photophysical strategy based on use molecular probes designed for single‐luminophore dual thermally activated delayed fluorescence (TADF). structural and conformational design makes TADF strong both diluted an...
Organic luminogens constitute promising prototypes for various optoelectronic applications. Since gaining distinct color emissions normally requires the alternation of conjugated backbone, big issues remain in material synthetic cost and skeleton compatibility while pursuing full-color luminescence. Upon a facile one-step coupling, three simple but smart perchalcogenated (O, S, Se) arenes are synthesized. They exhibit strong luminescent tricolor primaries (i.e., blue, green, red,...
Abstract Developing luminescent probes with long lifetime and high emission efficiency is essential for time‐resolved imaging. However, the practical applications usually suffer from quenching of traditional luminogens in aggregated states, or weak aggregation‐induced type monomeric states. Herein, we overcome this dilemma by a rigid‐and‐flexible alternation design donor–acceptor–donor skeletons, to achieve thermally activated delayed fluorescence luminogen both state (quantum yield up 35.3...

Abstract Although photoluminescence imaging‐guided photodynamic therapy (PDT) is promising for theranostics, it easily suffers from tissue autofluorescence and PDT photoproducts. To develop time‐resolved imaging (TRI)‐guided with long‐lived emission pathways, like thermally activated delayed fluorescence (TADF), urgent but challenging, because of the triplet competition between radiative transition reactive oxygen species (ROS) production. Herein, skeleton‐homologous nanoparticles are...
