Carbon dots show potential in lighting and displays. However, only their fluorescence has been observed so far. Here we report the observation of phosphorescence from carbon a polyvinyl alcohol matrix. The is attributed to CO bonds on surface very long lifetime (∼380 ms).
A visual colorimetric dipicolinic acid sensor was prepared by modulating the energy transfer process in MOF.
Abstract The experimental investigation of intermolecular charge transport in π‐conjugated materials is challenging. Herein, we describe the through and intramolecular paths single‐molecule single‐stacking thiophene junctions by mechanically controllable break junction (MCBJ) technique. We found that ability for different was approximately independent molecular structure, which contrasts with strong length dependence conductance same building blocks, dominant charge‐transport path molecules...
With the emergence of fused ring electron acceptors, power conversion efficiency organic solar cells reached 19%. In comparison with donor and acceptor materials progress, development cathode interlayers lags. As a result, charge extraction barriers, interfacial trap states, significant transport resistance may be induced due to unfavorable interlayer, limiting device performances. Herein, hybrid interlayer composed PNDIT-F3N PDIN is adopted investigate interaction between photoexcited...
A novel fluorescent chemosensor based on rhodamine derivative (Rh1) has been designed and synthesized for detection of Hg2+ ions, which exhibits high sensitivity selectivity over other metal ions in aqueous solution living cells. Moreover, this "Off–On"-type sensor could successfully mimic a molecular level keypad lock the presence Cu2+ ions. Stimulated by two chemical inputs (Hg2+ Cu2+), Rh1 undergoes transformation structure between spirocyclic ring-opened spirocyclic, results change...
A simple oligothiophene donor (Tz6T) was developed for organic solar cells. The devices with Tz6T achieved power conversion efficiencies (PCEs) of up to ca. 15.4%, representing one the crest values by donors.
Abstract Responsive molecular devices are one of the core units for electronics, and dynamic covalent bonds (DCBs) provide opportunity fabrication responsive devices. Herein we employ a single acyl hydrazone bond to fabricate tailored using scanning tunneling microscopy break‐junction technique (STM‐BJ) eutectic Ga‐In (EGaIn). We found that single‐DCB‐tailored exhibited acid‐base and/or photo‐thermal response with three well‐defined conductance states. The reversible switching has ON/OFF...
Under 980 nm excitation, cysteine could be detected with high sensitivity based on the FRET process donor UCNPs and acceptor rhodamine.
A volatile solid additive, 2,6-dichloroiodobenzene (DCIB), was introduced into PM6:Y6-based devices, and a better phase separation morphology gained due to the enhanced intermolecular interaction prospective stability with little decay during 25 days.
Active layer morphology is critical to determine the photovoltaic performance of organic solar cells (OSCs), and additive‐assisted optimization one most widely used strategies fine tune donor–acceptor network in active layer. However, postprocessing procedures additive residues require additional efforts maintain device performance. Herein, a low‐cost, simple structural design volatile solid 2,5‐diiodothiophene demonstrated effectively optimize prompt photoelectric conversion efficiency...
This article reports the development of hybrid AlGaN-based self-powered solar-blind ultraviolet (UV) focal plane array (FPA) imaging photosensors from material growth and preparation to functional verification.

Highly efficient nondoped phosphorescent organic light-emitting devices (NPOLEDs) with triplet multiple quantum well structures are fabricated by using 4,4′-N,N′-dicarbazole-biphenyl and an iridium(III) complex as the potential barrier layer layer/light-emitting layer, respectively. Remarkably, such NPOLED optimized device configuration achieves reduced current efficiency roll-off, which slightly decreases from its peak value of 31.5 cd/A at 19.8 mA/cm2 to 29.2 100 mA/cm2. We attribute this...
Although most cellular polymers are made from thermoplastics using different foaming technologies, gelatin and many other natural can form hydrogels convert them to solids various techniques, of which differ traditional plastic foaming, so does their resulting structures. Cellular porous materials that often exhibit a combination desirable properties, including high specific surface area, biochemical activity, as well thermal acoustic insulation properties. Among hydrogels, gelatin-based...
The performance of organic solar cells mainly depends on the morphology active layer. Traditional solution‐processed layers have poor due to random distribution donor and acceptor materials during solution processing. In addition, halogenated solvents additives widely used in traditional fabrication processes will a huge impact human health environment. Herein, an all‐green solvent additive combination strategy is proposed assist control layer with sequential deposition (SD) technique....
