Advanced Science, Volume 13, Issue 36, 29 June 2026.A snap‐top delivery nanosystem based on an azobenzene metal–organic framework achieves targeted release of 6‐mercaptopurine via acid‐stable frameworks and hypoxia/pH dual‐responsive β‐cyclodextrin gates. This multifunctional platform integrates three synergistic mechanisms: precision drug delivery to inflammatory sites, intrinsic antioxidant properties

Structural conditions required for the bridge lithiation and substitution of a basic calix[4]arene
Beilstein Journal of Organic Chemistry, 2011 Lithiation and subsequent reaction with CO2 was applied to calix[4]arenes with different, equal or mixed, ether functions at the lower-rim site as well as tert-butylated or non-tert-butylated upper-rim positions. Whereas this reaction fails for symmetric
