Flexibility in metal–organic frameworks : a basic understanding [PDF]

open access: yes, 2019
Much has been written about the fundamental aspects of the metal-organic frameworks (MOFs). Still, details concerning the MOFs with structural flexibility are not comprehensively understood.

Surface Science Approaches to Molecular Nanostructures

open access: yesCHIMIA, 2009
The self-assembly of large organic adsorbates on solid surfaces is driven by subtle energy balances between adsorbate–adsorbate and adsorbate–substrate interactions.

Suppression of anthropogenic secondary organic aerosol formation by isoprene

open access: yesnpj Climate and Atmospheric Science, 2022
Secondary organic aerosol (SOA) represents a major fraction of atmospheric fine particles. Both biogenic and anthropogenic volatile organic compounds (VOCs) can contribute to SOA through (photo-) oxidation.

Prebiotic Chemistry: Geochemical Context and Reaction Screening

open access: yesLife, 2013
The origin of life on Earth is widely believed to have required the reactions of organic compounds and their self- and/or environmental organization. What those compounds were remains open to debate, as do the environment in and process or processes by ...

An examination of the nature of localized molecular orbitals and their value in understanding various phenomena that occur in organic chemistry [PDF]

open access: yesJournal of Molecular Modeling, 2018
While canonical molecular orbitals have been used in computational chemistry for almost a century, the use of localized molecular orbitals is relatively new, and generating them has been difficult until recently. This has impeded their routine use in modeling chemical systems and reactions so that, even though localized molecular orbitals can now be ...

Selective detection of fluoride based on a pyridinium n-phenolate-calix[4]pyrrole displacement assay: an undergraduate laboratory experiment

open access: yesQuímica Nova, 2014
A two-step experiment is proposed for a third year class in experimental organic chemistry. Over a period of five weeks, the students synthesized calix[4]pyrrole, a receptor that is highly selective for fluoride, and a pyridinium N-phenolate dye ...
