Abstract In the boundary lubrication regime, the addition of long as well as straight alkyl chain containing additive exhibit a serendipitous impact on protecting various metallic surfaces or machinery components from friction and subsequent wear. In quest of environment-friendly, proficient friction-reducing, surface protective and cost-effective lubricant additives; herein, two diazomethine functionalised long-chain consisting organic molecules, namely (3E)-N-((E)-2-(octadecylimino)ethylidene)octadecan-1-amine (ODE) and (3E)-N-((E)-2-(dodecylimino)ethylidene)dodecan-1-amine (DDE) were synthesized through a one-pot condensation reaction. The surface protective film-forming, as well as wear and friction reducing properties of these organic additives on steel balls within paraffin oil (PO), were thoroughly explored using a four-ball tester with variation in time, load and speed. The addition of these additives showed a remarkable reduction of coefficient of friction (COF) and wear amount in compared to the pure base oil. ODE exhibited better performance with a ∼62% reduction in COF and ∼23% reduction in wear amount for steels in contact. Electronic level analysis for elucidating the tribofilm formation capability of the additives was rationalized using computational approaches such as density functional theory (DFT) and Fukui indices. Additionally, the molecular dynamics (MD) simulation which is an efficient computational approach was used to explore the spontaneous adsorption insight of additives; and also radial distribution function (RDF) were analysed to impressively explore the molecular-level interactions and adsorption mechanism of the additives with the metal atoms. Thereby, the mechanism of surface adhesive tribofilm formation and its metal protection capability has been explained in a comprehensive manner. Highlights Diazomethine functionalised organic molecules were synthesized with a variation of aliphatic chain length. Long aliphatic chain containing ODE additive showed enhanced surface protective performances in paraffin oil exhibiting lower COF value in comparison to DDE. Possible formation of ODE-based efficient tribofilm in metal-solution interface which exhibits enhanced surface adsorption property on the metal surface. Substantial decrease in wear upon addition of ODE in the base oil, which was confirmed by FE-SEM and 3D surface profilometer study. MD simulation has been used to investigate the adsorption competence of ODE and DDE on the iron surface.

Herein, two luminescent porous networks (CMERI-1 & CMERI-2) have been reported for the efficient detection of formaldehyde (FA) from aqueous medium. Judicious solvent screening using a high-throughput solvothermal procedure leads to two completely different metal-organic framework (MOFs) with different architectures. It is perceived that the framework CMERI-1 shows better sensitivity with a very short response time (1 min) in the realm of FA detection due to the facile imine (-N═CH-) formation, which is restricted in the case of CMERI-2. The fluorescence "turn-on" behavior is ascribed due to the inhibition of photoinduced electron transfer (PET) (from amine subunit to secondary building unit) process. The detection limits of CMERI-1 & CMERI-2 toward FA in aqueous medium were found to be 0.62 μM (0.019 ppm) and 1.39 μM (0.041 ppm), respectively, that lie far below the intracellular concentration of formaldehyde (100-400 μM). In addition, MOF-based hydrogel membrane was fabricated, which shows vapor-phase detection of FA, which is hitherto unexplored in this realm. Moreover, the response mechanisms of MOFs are supported by density functional theory (DFT) and Fukui indices analysis. The high stability of the porous frameworks along with its interesting sensing features such as fast recognition phenomenon, appreciable detection limit, etc. instigated us to explore its real-world applicability in various food sample and water analyses. In view of the modular design principle of our polymeric probe, the proposed approach could open a new horizon to construct powerful sensing materials for the ultrafast detection of other industrial pollutants in the domain of supramolecular and analytical chemistry.
