  • 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: 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

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.

[1][2][3]

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:

  1. Modulation of assembly processes: MSE achieves this by precisely adjusting the conformations of building blocks through intramolecular strain.
  2. Manipulation of reaction progress and selectivities: MSE fine-tunes the energy diagram of a reaction through intramolecular strain, thereby influencing its progress and selectivity.
  3. 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

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:
    • Molecular-strain engineering of double-walled tetrahedra.[1]
    • Tuning atropisomeric conversion in supramolecular structures.[4]
  • 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]
