Confining Molecules within Aqueous Coordination Nanoparticles by Adaptive Molecular Self‐Assembly

Dying on the inside: Functional dye molecules can be adaptively encapsulated in coordination nanoparticles (CNPs) of nucleotides and lanthanide ions in the course of their formation in water (see picture). Dyes confined in CNPs are conformationally restricted and surprisingly stable against molecular oxygen. These properties should be favorable for the development of light-harvesting CNPs.
