Steric effect of intermediates induces formation of three-dimensional covalent organic frameworks [PDF]
Nature CommunicationsConstructing three-dimensional covalent organic frameworks (3D COFs) remains a significant challenge compared to other areas of reticular chemistry. Most existing methods for constructing 3D COFs emphasize the necessity of at least one precursor being ...

Steric Effect of Antioxidant Diels-Alder-Type Adducts: A Comparison of Sanggenon C with Sanggenon D [PDF]
Molecules, 2018 Sanggenons C and D are two Diels-Alder-type adducts from Chinese crude drug Sang-bai-pi. Structurally, both sanggenons construct stereoisomers. In the study, they were comparatively determined using four antioxidant assays, including ferric ion reducing ...

Review and Modification of Entropy Modeling for Steric Effects in the Poisson-Boltzmann Equation
Entropy, 2020 The classical Poisson-Boltzmann model can only work when ion concentrations are very dilute, which often does not match the experimental conditions.

Ferrocenoyl-adenines: substituent effects on regioselective acylation
Beilstein Journal of Organic Chemistry, 2022 A series of N6-substituted adenine–ferrocene conjugates was prepared and the reaction mechanism underlying the synthesis was explored. The SN2-like reaction between ferrocenoyl chloride and adenine anions is a regioselective process in which the product ...
