A PCE of 5.16% with a <italic>V</italic><sub>oc</sub> 1.14 V is achieved thermally stable P3HT : SF(DPPB)<sub>4</sub> solar cells.
This work focuses on developing diketopyrrolopyrrole (DPP)‐based small molecular nonfullerene acceptors for bulk heterojunction (BHJ) organic solar cells. The materials, SF‐DPP s, have an X‐shaped geometry arising from four DPP units attached to a spirobifluorene (SF) center. spiro‐dimer of DPP‐fluorene‐DPP is highly twisted, which suppresses strong intermolecular aggregation. Branched 2‐ethylhexyl (EH), linear n ‐octyl (C8), and ‐dodecyl (C12) alkyl sides are chosen as substituents...
A donor–acceptor polymer with broad absorption from 300 to 1700 nm as a photothermal material toward highly efficient solar-driven water evaporation.
Electron-rich (donor) and electron-deficient (acceptor) units to construct donor–acceptor (D–A) conjugated macrocycles were investigated elucidate their interactions with fullerene. Triphenylamine 4,7-bisthienyl-2,1,3-benzothiadiazole alternately linked through acetylene, as the donor acceptor units, respectively, for pentagonal 3B2A hexagonal 4B2A macrocycles. As detected by scanning tunneling microscopy, both D–A found form an interesting concentration-controlled nanoporous monolayer on...
Two novel organogelators based on 2,3,4,5-tetraphenylsilole functionalized with long-chain alkoxydiacylamido platforms (1a and 1b) were synthesized. The silole derivatives induced gelation of only hydrocarbon solvents showed aggregation-induced emission (AIE) in the gel state, contrast to very weak solution. polarized optical microscopic (POM) field scanning electron microscopy (FE-SEM) studies exhibited that xerogels formed fibrous structures. Hydrogen bonding π-stacking interactions main...
Two novel solution-processable acceptor-donor-acceptor (A-D-A)-structured organic small molecules with diketopyrrolopyrrole (DPP) as terminal acceptor units and pentathiophene (PTA) or pyrrole-modified (NPTA) the central donor unit, namely, DPP2(PTA) DPP2(NPTA), were designed synthesized. We examined effects of changing bridging heteroatoms five-ring-fused thienoacene core identity from sulfur [DPP2(PTA)] to nitrogen [DPP2(NPTA)] in small-molecule material. Replacement atom a different...

Fullerenes have been recognized as good candidates for solid lubricants. In this study, the microscale superlubricity of fullerene derivatives was accomplished by construction regular host–guest assembly structures. Herein, structures were successfully constructed on a highly oriented pyrolytic graphite (HOPG) surface introducing macrocycles templates and explicitly revealed scanning tunneling microscopy (STM). Meanwhile, nanotribological properties assemblies measured using atomic force...
Abstract A series of linear 2,5‐tetraphenylsilole‐vinylene‐type polymers were successfully synthesized for the first time. The tetraphenylsilole moieties linked at their 2,5‐positions through a vinylene bridge with p ‐dialkoxybenzenes to obtain polymer PSVB and 3,6‐carbazole PSVC . For comparison, 2,5‐tetraphenylsilole‐ethyne‐type PSEB was also synthesized, in which replaced an ethyne bridge. Very interestingly, bridging group (vinylene or ethyne) had significant effect on photophysical...
We have designed and synthesized one molecular building block, an aromatic trialdehyde derivative with three aldehyde groups, to form a potentially active structure. The scanning tunneling microscopy (STM) images show that the forms lamellar structures. By addition of reactant, 5-aminoisophthalic acid, it is found structure adlayer can be transformed from hexagonal as was expected. structural formation networks attributed condensation reaction between amine. Density functional theory (DFT)...
The optoelectronic properties of the cruciform p–n diblock oligomers 1–3 can be independently tuned by oligofluorene and oxadiazole branches to increase charge mobility.
We present a method for the modification of structure thieno[3,4-c]pyrrole-4,6-dione (TPD) to gain two novel acceptors TPN and TIN. And series donor–acceptor–donor-type oligomers 3TTPD3T, 3TTPN3T, 3TTIN3T, based on TPD, TIN, have been designed synthesized solution-processed small-molecule bulk-heterojunction (BHJ) solar cells. The impact these different central acceptor moieties their optical, electrochemical properties, morphology, cell performance were studied. Optical data showed that...
The pyrene core and significantly reduced intramolecular steric hindrance endow a nonfused PDI-tetramer with moderate planarity good self-assembly properties.
We report herein a series of macrocycles in which the densely π-stacked charge-transfer (CT) donor/acceptor with naphthalenediimides (NDIs) or perylene diimide (PDI) as acceptor moiety pairing various donor moieties are locked by covalent bond. The X-ray crystallography C8BDT-NDI reveals short intramolecular π-stacking distance around 3.4 Å and existence intermolecular (3.7 Å). CT is highly dependent on electron-donating ability replacing carbazole (C8KZ) benzo[1,2-b:4,5-b']dithiophene...
Abstract A six-membered chelated iridium complex containing aza-aromatic ligand is prepared. Emission color tuning from yellow to deep red observed for electroluminescent devices with different doping concentrations.
A novel series of ladder π-conjugated materials--sila-pentathienoacenes (Si-PTA) are synthesized and characterized. Crystal structures the compounds show that length alkyl chains substituting on thiophene ring has a significant influence molecular packing. densely packed structure with an interfacial distance about 3.66 Å between adjacent molecules is observed for compound shorter chains. However, large (7.99 Å) obtained another because insertion long two planes. The investigation optical...
Abstract The cross‐shaped p–n diblock oligomers based on oligothiophenes (OTs) and 1,3,4‐oxadiazole (OXD) were synthesized investigated regarding optical properties, electrochemistry, quantum chemical calculations, intramolecular energy transfer. Since only one emission peak is observed in PL spectra of the oligomers, it evidenced that effective transfer from OXD to OTs branch. electrochemical experiments show almost complete spatial separation HOMO LUMO with thiophene number increasing....
