| Submission declined on 8 October 2022 by Timtrent (talk). I'm struggling with this. You have added a small amount of material since asked to produce more information, but I am failing to see even a stub article here, the minimum standard for acceptance.
I'm not sure what the numbered section is meant to show. Using Google Scholar, this appears to be a new field, with a very small number of citations of the various papers It appears that the author may be one of the authors of papers in this area. This makes matters difficult, because if the conflict of interest that this produces if correct. Wikipedia is not a place to promote one's original work. So where do you go from here? Improved content and, ideally, more substantial coverage about the topic. We also need the reader to know what the topic is about in words for the generalist reader, and this should happen in the lead section. | |
| Submission declined on 23 May 2022 by HenryTemplo (talk). The proposed article does not have sufficient content to require an article of its own, but it could be merged into the existing article on the same subject. Since anyone can edit Wikipedia, you are welcome to add that information yourself. Thank you. | |
Comment: I attempted to edit the article, but according to the copyvio report, most of the article's content is copied from the faculty page of one of the researchers, Dr Zhichang Liu, maintained at Westlake University. If we look at the creator's ID, there is a good chance that the researcher is the one who is actually putting together this page. RPSkokie (talk) 08:07, 22 January 2023 (UTC)

- Comment: I agree with the other editors here, without context or many references and with how short this article is, I don't think it has substantial coverage for an article yet CodeLyokotalk 03:33, 8 November 2022 (UTC)
- Comment: You have resubmitted this without doing the work required. Please actually read and understand prior reviews and act on them of you wish this to have a chance of acceptance 🇺🇦 FiddleTimtrent FaddleTalk to me 🇺🇦 12:52, 7 November 2022 (UTC)
- Comment: As Timtrent mentioned before, there is a very small amount of content on this submission. The citations are reliable but I struggle to see notability on this one. Perhaps elaborating on the topic more may be a good idea. Eternal Shadow Talk 04:20, 10 October 2022 (UTC)

Background edit
In the field of chemistry, strain refers to the stress experienced by the chemical structure of a molecule, resulting in an increase in its internal energy compared to a reference compound without strain.
Precise control over molecular strain enables fine-tuning of mechanical, electrical, and optical characteristics, opening up possibilities for tailoring materials to specific applications and requirements.
Exploring molecular strain entails delving into the fundamental interactions and behaviors of molecules, deepening our understanding of molecular dynamics and contributing to scientific progress.
In conclusion, molecular-strain engineering represents a captivating and valuable area of research.
Molecule-Strain Engineering (MSE) is a promising approach that can be utilized in three main aspects:
- Modulation of assembly processes: MSE achieves this by precisely adjusting the conformations of building blocks through intramolecular strain.
- Manipulation of reaction progress and selectivities: MSE fine-tunes the energy diagram of a reaction through intramolecular strain, thereby influencing its progress and selectivity.
- Modulation of physical and chemical properties: MSE modifies the fundamental geometrical parameters of molecules, such as bond length and valence angle, resulting in changes in their physical and chemical properties.
Mechanisms edit
MSE aims to understand the mechanisms and principles behind how mechanical strain affects molecular behaviors and properties. It involves the following:
- Control of supramolecular assembly processes:
- Manipulation of reaction progress and selectivities through MSE:
- Mechanical trapping of the phlorin intermediate.[2]
- Mechanical trapping and in situ derivatization of the porphodimethene intermediate.[3]
- Tunable force-directed bond cleavage strategy through MSE.[5]
- Modulation of physical and chemical properties of molecules through MSE:
- Mechanically tuning spin crossover property within molecular knots.[6]
- Tuning photophysical properties by varying intramolecular strain.[7]
- Strain-induced enhancement in reactivity of molecules.[8]
