| 1 | High-performance all-polymer solar cells enabled by a novel low bandgap non-fully conjugated polymer acceptor显示文摘The non-fully conjugated polymer as a new class of acceptor materials has shown some advantages over its small molecular counterpart when used in photoactive layers for all-polymer solar cells(all-PSCs),despite a low power conversion efficiency(PCE)caused by its narrow absorption spectra.Herein,a novel non-fully conjugated polymer acceptor PFY-2TS with a low bandgap of~1.40 eV was developed,via polymerizing a largeπ-fused small molecule acceptor(SMA)building block(namely YBO)with a non-conjugated thioalkyl linkage.Compared with its precursor YBO,PFY-2TS retains a similar low bandgap but a higher LUMO level.Moreover,compared with the structural analog of YBO-based fully conjugated polymer acceptor PFY-DTC,PFY-2TS shows a similar absorption spectrum and electron mobility,but significantly different molecular crystallinity and aggregation properties,which results in optimal blend morphology with a polymer donor PBDB-T and physical processes of the device in all-PSCs.As a result,PFY-2TS-based all-PSCs achieved a PCE of 12.31%with a small energy loss of 0.56 eV enabled by the reduced non-radiative energy loss(0.24 eV),which is better than that of 11.08%for the PFY-DTC-based ones.Our work clearly demonstrated that non-fully conjugated polymers as a new class of acceptor materials are very promising for the development of high-performance all-PSCs. | Qunping Fan Ruijie Ma Tao Liu Jianwei Yu Yiqun Xiao Wenyan Su Guilong Cai Yuxiang Li Wenhong Peng Tao Guo Zhenghui Luo Huiliang Sun Lintao Hou Weiguo Zhu Xinhui Lu Feng Gao Ellen Moons Donghong Yu He Yan Ergang Wang | 2021 | Science China Chemistry2021，64，8： | 3 |

| 5 | Effects of Flexible Conjugation-Break Spacers of Non-Conjugated Polymer Acceptors on Photovoltaic and Mechanical Properties of All-Polymer Solar Cells显示文摘All-polymer solar cells(all-PSCs)possess attractive merits including superior thermal stability and mechanical flexibility for large-area roll-to-roll processing.Introducing flexible conjugation-break spacers(FCBSs)into backbones of polymer donor(P_(D))or polymer acceptor(P_(A))has been demonstrated as an efficient approach to enhance both the photovoltaic(PV)and mechanical properties of the all-PSCs.However,length dependency of FCBS on certain all-PSC related properties has not been systematically explored.In this regard,we report a series of new non-conjugated P_(A)s by incorporating FCBS with various lengths(2,4,and 8 carbon atoms in thioalkyl segments).Unlike com-mon studies on so-called side-chain engineering,where longer side chains would lead to better solubility of those resulting polymers,in this work,we observe that the solubilities and the resulting photovoltaic/mechanical properties are optimized by a proper FCBS length(i.e.,C2)in P_(A) named PYTS-C2.Its all-PSC achieves a high efficiency of 11.37%,and excellent mechanical robustness with a crack onset strain of 12.39%,significantly superior to those of the other P_(A)s.These results firstly demonstrate the effects of FCBS lengths on the PV performance and mechanical properties of the all-PSCs,providing an effective strategy to fine-tune the structures of P_(A)s for highly efficient and mechanically robust PSCs. | Qiaonan Chen Yung Hee Han Leandro R.Franco Cleber F.N.Marchiori Zewdneh Genene CMoyses Araujo Jin-Woo Lee Tan Ngoc-Lan Phan Jingnan Wu Donghong Yu Dong Jun Kim Taek-Soo Kim Lintao Hou Bumjoon J.Kim Ergang Wang | 2022 | Nano-Micro Letters2022，14，10： | 1 |
| 6 | Revealing HOC1 burst from endoplasmic reticulum in cisplatin-treated cells via a ratiometric fluorescent probe显示文摘The reactive oxygen species(ROS) are tightly associated with endoplasmic reticulum(ER) stress.Thus,the deep and visual insight of aberrant ROS fluctuations in the ER can help us better investigate the ER stress-associated pathology.In this work,a fluorescent probe ERC for HOCI detection in the ER based on phenothiazine-derived coumarin platform was developed.In the presence of HOCI,ERC exhibited an emission change from 609 nm to 503 nm within seconds.It also showed high sensitivity(0.44 μmol/L)and superb photostability.Significantly,ERC displayed low cytotoxicity,good cell membrane permeability,and appreciable ER-targetability.Ultimately,the probe was successfully utilized to image exogenous and endogenous HOCl in living cells and reveal the HOCI burst in cisplatin-treated cancer cells. | Shan Wang Beitong Zhu Bingya Wang Xinhua Cao Lei Zhu Ji-Ting Hou Lintao Zeng | 2021 | Chinese Chemical Letters2021，32，5： | 1 |

| 9 | Novel Hybrid Ligands for Passivating Pb S Colloidal Quantum Dots to Enhance the Performance of Solar Cells显示文摘We developed novel hybrid ligands to passivate Pb S colloidal quantum dots(CQDs),and two kinds of solar cells based on as-synthesized CQDs were fabricated to verify the passivation effects of the ligands.It was found that the ligands strongly affected the optical and electrical properties of CQDs,and the performances of solar cells were enhanced strongly.The optimized hybrid ligands,oleic amine/octyl-phosphine acid/Cd Cl2improved power conversion efficiency(PCE)to much higher of 3.72%for Schottky diode cell and 5.04%for p–n junction cell.These results may be beneficial to design passivation strategy for low-cost and high-performance CQDs solar cells. | Yuehua Yang Baofeng Zhao Yuping Gao Han Liu Yiyao Tian Donghuan Qin Hongbin Wu Wenbo Huang Lintao Hou | 2015 | Nano-Micro Letters2015，7，4： | 0 |
| 10 | Colorless-to-colorful switching of electrochromic MXene by reversible ion insertion显示文摘Electrochromic(EC)materials that change color with voltage have been widely studied for use in dynamic windows.However,colorless-to-colorful switching with high contrast ratio is generically unattainable,especially for colorless-to-black electrochromic materials with an ultrahigh contrast ratio over the entire visible region.In this work,we developed Nb_(1.33)C MXene-based dynamic windows with colorless-to-black switching of up to 75%reversible change in transmittance from 300 to 1,500 nm.By exploring the electrochromic effects of different electrolytes through in situ optical changes and electrochemical quartz crystal microbalance(EQCM),it is found that electrochromic behavior is greatly influenced by the extent of reversible Li^(+)insertion/deinsertion between the two-dimensional Nb_(1.33)C MXene nanosheets.In addition,a colorless-to-black EC device based on Nb_(1.33)C with an overall integrated contrast ratio over 80%was successfully constructed by a solution-processable spin coating method.This work enables a simple route to fabricate MXene-based high-performance electrochromic smart windows,which is important for further expanding the application of MXenes to optoelectronic and photonic applications. | Jianxia Jiang Leiqiang Qin Joseph Halim Per O.Å.Persson Lintao Hou Johanna Rosen | 2022 | Nano Research2022，15，4： | 0 |
