Summary: The study explored a series of amphiphilic indoline-based unsymmetrical squaraine dyes, where alkyl groups and glycolic chain were systematically modified to control self-assembly and improve interfacial properties. In nonaqueous DSSCs, increasing the number of carbon atoms in alkyl groups enhanced photovoltaic efficiencies. Addition of chenodeoxycholic acid improved efficiency, while increased carbon atoms in the alkyl groups had a detrimental effect on aqueous DSSC efficiency.

Summary: This paper presents a computational study on the modification of low-energy-gap benzoindenothiophene (BIT)-based dyes with fused thiophene moieties to build novel low band gap sensitizers. The results show that the structural modification by using fused thiophenes can effectively lower the band gap of the BIT dyes and affect their optical properties. The incorporation of different thiophene units in BIT dyes improves the oscillator strength while maintaining the lowest-energy absorption peak. The introduction of the cyclopentadithiophene unit leads to a significant red-shift of absorption peak and enhanced oscillator strength. These modified BIT dyes also demonstrate ideal molecular orbital distribution patterns and ultra-fast injection time at the dye/(TiO2)46 interface.

Summary: We reported three newly synthesized D-A-π-A metal-free organic sensitizers for dye-sensitized solar cells (DSSCs) based on benzo[c][1,2,5]thiadiazole as an internal acceptor (A) and N-substituted indolines fused with cyclopentane or cyclohexane as donor (D) building block. Optical and photovoltaic properties of the new MAX series dyes and solar cells based on them were studied, showing that the MAX157 dye with a 9-(2-ethylhexyl)-2,3,4,4a,9,9a-hexahydro-1H-carbazole donor fragment has a shorter-wavelength absorption maximum in the intra-molecular charge transfer absorption band with the largest molar extinction coefficient among the dyes studied. The DSSCs based on MAX157 dye recorded the best power conversion efficiency (PCE) of 5.2%, which increased to 5.8% when co-sensitized with SQ2 dye.

Summary: In this study, six novel D-A-D type HTMs and three thiophene-substituted acceptors were designed and the influences of acceptor moiety on HTMs performance were investigated through theoretical chemical calculations. The results showed that the designed HTMs exhibited more negative HOMO energy levels and slightly red-shifted light absorption, with a small torsion angle between the acceptor and donor proving beneficial for hole transport and charge mobility enhancement. Moreover, the large charge transfer amounts and small exciton binding energies of the HTMs may facilitate electron-hole separation, although their stability could be compromised according to the calculated electrostatic surface potential and absolute hardness results.

Summary: Ordered monolayer ionic liquid coatings can achieve ultralow friction and exhibit good structure recoverability under high pressure. This extreme lubrication is primarily due to the ordered striped structure driven by the atomic-locking effect between the carbon atoms on the alkyl chain of the ionic liquid and graphite. Controlling the alkyl chain length and stripe periodicity is crucial in reducing energy dissipation.

Summary: This study evaluates the strategy of extending and rigidifying the acceptor in donor-acceptor-donor-type hole-transporting materials (HTMs) to improve their performance. Theoretical calculations show that the predicted HTMs have suitable energy levels for easy hole transfer at the perovskite/HTM interface. Extending the acceptor group and rigidifying the conjugated acceptor can both enhance the hole mobility of HTMs. The predicted HTMs have higher hole mobility and matched energy levels, which are favorable for improving the performance of perovskite solar cells (PSCs).

Summary: The Ru-catalyzed carbonylation of alkenes using CO2 and imidazole chlorides as the promotor was studied through computational and experimental analysis. The efficiency of hydroesterification and hydroformylation was found to be correlated with the conversion rate of CO2 to CO, which was facilitated by chloride additives, particularly BmimCl and B3MimCl > BmmimCl > LiCl. In the hydroesterification reaction with MeOH, BmimCl with C-H functionality at the C2 site of the cation acted as a hydrogen donor medium, with the anion and cation working synergistically. The insertion of CO2 into the formed Ru-H bond with the assistance of chloride anion produced the Ru-COOH species, accelerating the activation of CO2.

Summary: Ionic liquids (ILs) are investigated for their potential as efficient biomolecular solvents, with the interaction mechanism between ILs and a hydrophobic zwitterionic amino acid (Tyr) studied using density functional theory (DFT) calculations. The results reveal that the interaction between IL cations and Tyr is dominated by hydrogen bonding, while electrostatic effects play a key role in the binding of IL anions with Tyr. The study also shows that the methylation site on the imidazolium ILs influences the interaction pattern with Tyr, with different contributions from induction and dispersion forces.
