Chemical transferability of functional groups follows from the nearsightedness of electronic matter [Chemistry]
We establish the physical origins of chemical transferability from the perspective of the nearsightedness of electronic matter.
To do this, we explicitly evaluate the response of electron density to a change in the system, at constant chemical potential,
by computing the softness kernel,
s(𝐫,𝐫′). The softness kernel is nearsighted, indicating that under constant-chemical-potential conditions like dilute solutions changing
the composition of the molecule at
𝐫 has only local effects and does not have any significant impact on the reactivity at positions
𝐫′ far away from point
𝐫. This locality principle elucidates the transferability of functional groups in chemistry.

Keeping up-to-date with research can feel impossible, with papers being published faster than you'll ever be able to read them. That's where Researcher comes in: we're simplifying discovery and making important discussions happen. With over 19,000 sources, including peer-reviewed journals, preprints, blogs, universities, podcasts and Live events across 10 research areas, you'll never miss what's important to you. It's like social media, but better. Oh, and we should mention - it's free.
Researcher displays publicly available abstracts and doesn’t host any full article content. If the content is open access, we will direct clicks from the abstracts to the publisher website and display the PDF copy on our platform. Clicks to view the full text will be directed to the publisher website, where only users with subscriptions or access through their institution are able to view the full article.
