Herein, we engineered eight new NF-SMAs (ABG1-ABG8) with a narrower band gap and improved intramolecular charge transfer (ICT). A systematic study has examined the structure-property relationship, optical, optoelectronics, and photovoltaic characteristics of these NF-SMAs using density functional theory (DFT) and time-dependent (TD-DFT). The photophysical parameters of the designed (ABG1-ABG8) materials were examined and compared with the standard molecule (ABGR). Further, we estimated frontier molecular orbitals, electrostatic potential, density of states, transition density matrix, and reorganization energy analysis. Compared to the synthetic reference molecule ABGR (2.03 eV), the designed acceptor series presented a smaller bandgap (E_g = 1.85–1.98 eV) and displayed a red shift in absorption maxima (<em>λ</em>_max 761.99–864.00 nm), respectively. The minimum value of the E_g for ABG3 and the maximum <em>λ</em>_max was for ABG6. Furthermore, the ABG1-ABG8 designed series shows a lower value of excitation energy (E_x) 1.43eV for ABG6 compared to the reference (E_x 1.72 eV). Additionally, these designed materials presented more efficient photovoltaic characteristics than reference ABGR molecule. The value of open-circuit voltage (<em>V</em>_<em>oc</em>) is maximum for ABG8 (1.55eV) while for all proposed molecules the value of (<em>V</em>_<em>oc</em>) is in the range of 1.19–1.55 V. Improved <em>V</em>_<em>oc</em> and fill factor values further enhance the overall power conversion efficiency of designed molecules compared to the ABGR molecule. The maximum value of PCE was for ABG8 among all newly designed molecules. To determine the charge-accepting ability of the designed molecules, we performed the donor:acceptor complex study using polymer donor PTB7-Th with the designed ABG6 molecule. Our findings demonstrate that newly developed non-fullerene-based materials (ABG1-ABG8) exhibit improved photovoltaic and optoelectronic features. Therefore, we recommend these engineered materials for next-generation efficient and cost-effective organic photovoltaics.</div></div>","PeriodicalId":18227,"journal":{"name":"Materials Chemistry and Physics","volume":"337 ","pages":"Article 130611"},"PeriodicalIF":4.3,"publicationDate":"2025-02-24","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143509966","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"材料科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

A Cu/10Sn5Bi alternating stripe coating with a KF-Ni15 transition layer was applied to 45 steel. The macroscopic morphology, microstructure, phase composition, microhardness, tribological properties, and wear mechanism of the alternating stripe coating were investigated. The results indicate that a very thin “hard band” (approximately 17 μm) forms at the interface between the Cu layer and the 10Sn5Bi layer, primarily composed of the Cu3Sn intermetallic compound, along with a small amount of Bi and Ni elements. XRD pattern analysis reveals that the alternating coating is primarily composed of free Bi, Cu3Sn, and CrC phases. The unique macroscopic morphology and microstructure of the alternating coating result in a surface hardness distribution of alternating soft and hard regions, enhancing the wear resistance of the coating. Compared to the pure copper coating, the friction coefficient of the Cu/10Sn5Bi alternating coating decreased significantly, reaching 0.39 with an increase in the filling rate of 10Sn5Bi. This result is primarily attributed to the high fluidity of free Bi, which promotes the formation of a friction film on the surface, the self-lubricating effect of Cu and 10Sn5Bi, and the supporting and pinning effects of the “hard band” containing Cu3Sn compounds, Ni, Bi, and other elements. This fully demonstrates that the alternating stripe structure design of the surface coating enhances the synergistic effects of lubrication and hard coating. The multi-phase coupling effect of 10Sn5Bi, free Bi, and Cu3Sn, formed by laser cladding the Cu/10Sn5Bi alternating stripe structure, imparts unique properties to the coating and offers valuable insights for the design and development of laser-cladded self-lubricating coatings.</div></div>","PeriodicalId":18227,"journal":{"name":"Materials Chemistry and Physics","volume":"337 ","pages":"Article 130601"},"PeriodicalIF":4.3,"publicationDate":"2025-02-23","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143510970","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"材料科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
