A highly efficient acceptor material for organic solar cells (OSCs) – based on perylene diimide (PDI) dimers shows significantly reduced aggregation compared to monomeric PDI. The dimeric PDI a best power conversion efficiency (PCE) approximately 300 times that of the when blended with conjugate polymer (BDTTTT-C-T) and 1,8-diiodooctane as co-solvent (5%). This non-fullerene materials also hold promise OSCs. As service our authors readers, this journal provides supporting information...

The widely used solvents of chloroform (CF) o-dichlorobenzene (o-DCB) were as the spin-coating solvent, respectively, 1,8-diiodooctane (DIO) was additive to fabricate efficient photovoltaic devices BDT-DPP donor material PC71BM acceptor material. Devices fabricated from CF exhibit poor fill factor (FF) 43%, low short-circuit current...

Abstract The elaborate balance between the open‐circuit voltage ( V OC ) and short‐circuit current density J SC is critical to ensure efficient organic solar cells (OSCs). Herein, chalcogen containing branched chain engineering employed address this dilemma. Three novel nonfullerene acceptors (NFAs), named BTP‐2O , BTP‐O‐S BTP‐2S featuring different peripheral chains are synthesized. Compared with symmetric grafting two alkoxy or alkylthio chains, asymmetric one shows mediate absorption...
A non-fullerene, all-small-molecule solar cell (NF-SMSC) device uses the blend of a small molecule donor and acceptor as active layer. Aggregation ability is key factor for this type cell. Herein, we used alkylthienyl unit to tune aggregation diketopyrrolopyrrole (DPP)-based donors. Replacing two alkoxyl units in BDT-O-DPP with yields BDT-T-DPP, further introducing another into backbone produces BDT-T-2T-DPP. With introduction alkylthienyl, becomes twisted. As result, ππ-stacking strength,...
Abstract Coumarins and its analogues have been widely used as chromophore in design of fluorescent probe, while less coumarin‐based probe was reported for detection anion water. In this article, probes with salicylaldehyde functionality recognition unit developed selective bisulfite anions Four novel were synthesized from 4‐haloresorcinol three steps. The chemoprobe exhibited response to over other anions. Moreover, the mechanism studied. Upon added, intensity enhanced highly due...
Solution-processed star-shaped triphenylamine (TPA) derivatives and dialkylated diketopyrrolopyrrole (DPP)-based small molecules have been widely studied because they both yield promising photon-to-electron conversion. However, the power conversion efficiency (PCE) of covalent TPA-DPP is still very low. To design with better photovoltaic performance, we embedded a thiophene ring in between TPA DPP units, namely TPA-T-DPP, reported comparative studies optoelectronic properties TPA-T-DPP....
Two amphiphilic and highly twisting perylene diimide (PDI) dimers, Bis-PDI-BDT-EG, were synthesized by using 4,8-bis(2-(2-ethylhexylthienyl) benzo[1,2-b:4,5-b′]dithiophene (BDT-T) 4,8-bis(2-ethylhexyloxy) BDT (BDT-O) as covalent bridges at the 7,7′-positions, while 1,1′-positions, they functionalized with weakly solvophobic 2-methoxylethoxyl (EG) units. The subtle structural differences between BDT-O BDT-T lead to distinct aggregation abilities: respect over-strong ability of bridged dimer...
Abstract Lithium metal batteries (LMBs) are inherently characterized by their high energy density, while the inventory loss of active lithium (Li) and affected cyclability have been impeding practical applications. Achieving a balance that simultaneously ensures long cycle life density is still challenge. Here different LMB geometries explored, specifically anode‐free, anode‐less, anode‐rich configurations with Li reservoirs in anode side, to address this trade‐off. An engineered...
Three solution-processable small molecules of DPPT, DPPSe and DPPTT were synthesized by Stille coupling through attaching donor units thiophene (T), selenophene (Se) thieno[3,2-b]thiophene (TT) to the diketopyrrolopyrrole (DPP) core, respectively. Replacement T donors with more polarized Se results in a balance between b direction packing an obvious increase power conversion efficiency (PCE) from 1.90% 2.33% short-circuit current (Isc) 5.59 5.81 mA cm−2 open-circuit voltage (Voc) 0.78 V 0.86...
Because of their outstanding molecular optoelectronic properties, perylene diimides (PDIs) are promising alternatives to the commonly used PCBM. However, overly strong aggregation ability, poor solution-processability and compatibility PDIs severely limit photovoltaic applications. We turned borrowing amphiphile concept improve these supramolecular properties. Practically, we fine-tuned solvophobicity with respect solvophilicity, e.g. Fsolvophob/solvophil, by changing number weakly...

Multicolor luminescence of organic fluorescent materials is an essential part lighting and optical communication. However, the conventional construction a multicolor system based on integrating multiple single emission band remains complicated to be improved. Herein, alloys (OAs) capable full-color are synthesized charge transfer (CT) cocrystals.
