Strategic design of a rare trigonal symmetric luminescent covalent organic framework by linker modification

The Journal of Chemical Physics, Год журнала: 2024, Номер 160(5)

Опубликована: Фев. 6, 2024

We designed a trigonal symmetric imine-linked covalent organic framework (COF), TFPC-DAB, with control over the angularity of building units, where bent C2-symmetric diamine, such as 1,3-diaminobenzene (1,3-DAB or DAB), an exo-angle 120° was used instead those 180°, in combination C3-symmetric trialdehyde, tri(4-formylphenoxy)cyanurate (TFPC). Its synthesis accomplished by reacting units mixture mesitylene/dioxane/6 M acetic acid under solvothermal conditions. The phase purity, thermal stability, and porosity TFPC-DAB were established various analytical techniques. Utilizing Density Functional Tight Binding (DFTB+) simulation Pawley refinement, best fit small angle x-ray pattern found to have AA stacking space group P3 low refinement parameters. Such smart materials are huge demand detect hazardous corrosive chemicals, HCl NH3. dual features electron deficient π-acidic triazine moiety heteroatoms (N/O) from TFPC rich phenyl DAB embodied enhance its luminescent property thereby make it suitable for solvent-based NH3 sensing. detection limits methanol be 14 82 ppb, respectively. effect solvent polarity on sensing studies observed much lower dioxane: 2.5 11 ppb NH3, A detailed theoretical calculation using density functional theory configurational bias Monte Carlo modules conducted understanding interactions between COF analytes.

‘As of my last knowledge update’: How is content generated by ChatGPT infiltrating scientific papers published in premier journals?

Learned Publishing, Год журнала: 2024, Номер 38(1)

Опубликована: Дек. 24, 2024

Abstract The aim of this paper is to highlight the situation whereby content generated by large language model ChatGPT appearing in peer‐reviewed papers journals recognized publishers. demonstrates how identify sections that indicate a text fragment was generated, is, entirely created, ChatGPT. To prepare an illustrative compilation appear indexed Web Science and Scopus databases possessing Impact Factor CiteScore indicators, SPAR4SLR method used, which mainly applied systematic literature reviews. Three main findings are presented: highly regarded premier journals, articles bear hallmarks AI models, whose use not declared authors (1); many these identified already receiving citations from other scientific works, also placed found (2); and, most belong disciplines medicine computer science, but there such as environmental engineering, sociology, education, economics management (3). This aims continue add recently initiated discussion on models like creation scholarly works.
