Ethyl 2-[4-(4-meth-oxy-benz-yl)-3-methyl-6-oxopyridazin-1-yl]acetate.
Zaoui Y, Assila H, Mague JT, Alsubari A, Taoufik J, Ramli Y, Ansar M. Zaoui Y, et al. IUCrdata. 2022 Jun 7;7(Pt 6):x220582. doi: 10.1107/S241431462200582X. eCollection 2022 Jun. IUCrdata. 2022. PMID: 36339895 Free PMC article.
In the title mol-ecule, C(17)H(20)N(2)O(4), the inner part of the ester substituent is nearly perpendicular to the di-hydro-pyridazine ring, forming a dihedral angle of 83.21 (7). In the crystal, inversion dimers are formed by pairwise C-HO inter-actions with the di …

Is pi halogen bonding or lone pair...pi interaction formed between borazine and some halogenated compounds?
Zhuo H, Li Q, Li W, Cheng J. Zhuo H, et al. Phys Chem Chem Phys. 2014 Jan 7;16(1):159-65. doi: 10.1039/c3cp54006e. Phys Chem Chem Phys. 2014. PMID: 24232521
It was known that benzene is favorable to form halogen bonds with halogenated molecules. However, borazine more easily forms lone pair-pi interactions with halogenated molecules, but for stronger halogen donors it can also form halogen bonds. The halogen bonds fo …

Aromatic Polyphenol pi-pi Interactions with Superoxide Radicals Contribute to Radical Scavenging and Can Make Polyphenols Mimic Superoxide Dismutase Activity.
Caruso F, Incerpi S, Pedersen J, Belli S, Kaur S, Rossi M. Caruso F, et al. Curr Issues Mol Biol. 2022 Oct 26;44(11):5209-5220. doi: 10.3390/cimb44110354. Curr Issues Mol Biol. 2022. PMID: 36354666 Free PMC article. Review.
Mechanistically, it is very difficult to establish if this pi-pi interaction proceeds before or after the most common mode of scavenging superoxide, e.g., abstraction of an aromatic polyphenol H(hydroxyl), which then is used to form H(2)O(2) (the other molecule prod …

Chromatofocusing.
Li CM, William Hutchens T. Li CM, et al. Methods Mol Biol. 1992;11:237-48. doi: 10.1385/0-89603-213-2:237. Methods Mol Biol. 1992. PMID: 21431670
The pH gradient is formed internally during isocratic elution with a single focusing buffer; no external gradient forming device is required. The pH gradient is formed as the eluting buffer (i.e., focusing buffer) titrates the buffering groups on the ion exch …

Thermal Transport in Poly(p-phenylene): Anomalous Dimensionality Dependence and Role of pi-pi Stacking.
Yang C, Raza S, Li X, Liu J. Yang C, et al. J Phys Chem B. 2023 Aug 3;127(30):6804-6813. doi: 10.1021/acs.jpcb.3c02947. Epub 2023 Jul 21. J Phys Chem B. 2023. PMID: 37478475
Intuitively, for chains with an aromatic backbone, the even stronger pi-pi stacking, once formed between chains, should enhance thermal transport across chains and suppress the thermal conductivity along the chains. ...We analyzed the probability distribution …
