| 1 | Solution-processed polymer photodetectors with trap-assisted photomultiplication显示文摘Here, we report a trap-assisted photomultiplication(PM) phenomenon in solution-processed organic photodetectors(OPDs) using poly(3-hexylthiophene)(P3HT): indene-C60 bisadduct(ICBA) as the active layer. The maximum external quantum efficiency(EQE) is 685% for the device with 2% ICBA doping ratio, which is much higher than that of OPDs with P3HT:ICBA(1:1) as the active layer. The PM phenomenon is attributed to the hole tunneling injection assisted by trapped electron in ICBA near Al cathode, which can be demonstrated from the EQE spectra and transient photocurrent curves of OPDs with different ICBA doping ratios. | HAN ZiHong ZHANG Hui TIAN QiuShuo LI LingLiang ZHANG FuJun | 2015 | Science China(Physics,Mechanics & Astronomy)2015，58，5： | 1 |
| 2 | Logic-Gated Plasmonic Nanodevices Based on DNA-Templated Assembly显示文摘Life has evolved numerous elegant molecular machines that recognize biological signals and affect mechanical changes precisely to achieve specific and versatile biofunctions.Inspired by nature,synthetic molecular machines could be designed rationally to realize nanomechanical operations and autonomous computing.We constructed logic-gated plasmonic nanodevices through coassembly of two gold nanorods(AuNRs)and computing elements on a tweezer-shaped DNA origami template.After recognition of various molecular inputs,such as DNA strands,glutathione,or adenosine,the geometry and plasmonic circular dichroism(CD)signals of the AuNR–origami nanodevices produced corresponding changes.Then we designed and characterized a set of modular Boolean logic-gated nanodevices(YES,NOT,AND,OR)and proceeded to construct a complicated 3-input circuit capable of performing Boolean OR-NOT-AND operations.Our plasmonic logic devices transduced external inputs into conformational changes and near-infrared(NIR)chiral outputs.This DNA-based self-assembly strategy holds great potential for applications in programmable optical modulators,molecular information processing,and bioanalysis. | Fengsong Liu Qiao Jiang Qing Liu Na Li Zihong Han Chao Liu Zhaoran Wang Yunfei Jiao Jiashu Sun Baoquan Ding | 2021 | CCS Chemistry2021，3，3： | 0 |
