TL;DR: Nonscattering glasses that are indefinitely stable with respect to crystallization can be prepared from the title compounds because the dendritic substituents effectively suppress interactions between the phthalocyanine units.
Abstract: Nonscattering glasses that are indefinitely stable with respect to crystallization can be prepared from the title compounds. In these solid solutions, the dendritic substituents effectively suppress interactions between the phthalocyanine units (see the structure depicted on the right).

TL;DR: Nichtstreuende Glaser, die bezuglich Kristallisation unbegrenzt stabil sind, lassen sich aus den Titelverbindungen herstellen as discussed by the authors.
Abstract: Nichtstreuende Glaser, die bezuglich Kristallisation unbegrenzt stabil sind, lassen sich aus den Titelverbindungen herstellen. In diesen festen Losungen verhindern die dendritischen Substituenten wirksam starkere Wechselwirkungen zwischen den Phthalocyanin-Einheiten (siehe rechts).

TL;DR: The use of tetramethylpropanediammonium (2+) or hexaamminecobalt (III) as counter cations allowed the preparation of monomeric or dimeric uranyl bis(dimethylmalonato) complexes, respectively, which were characterised by solid-state 13 C NMR and X-ray crystallography as mentioned in this paper.
