Konstruktion hochselektiver Bindungstaschen in UiO‐Typ‐MOFs mittels verbrückter Linker

open access: yesAngewandte Chemie, EarlyView.
Großer Gestaltungsspielraum: Es wird eine generelle Strategie für die präzise ortsspezifische Modifikation von UiO‐Typ‐MOFs mit funktionellen Gruppen vorgestellt. Durch den Einsatz von vorverbrückten oder pre‐connected Linkern werden gezielt taschenartige Poren für die molekulare Erkennung erzeugt, deren hohe Affinität gegenüber aliphatischen ...

Formation of Highly Selective Binding Pockets in UiO‐Type MOFs From Bridged Linkers

open access: yesAngewandte Chemie International Edition, EarlyView.
Much room for design: We present a generalizable strategy for precisely modifying UiO‐type Metal‐organic frameworks with functional groups in a site‐specific manner. Through the use of pre‐connected linkers, pocket‐like pores for molecular recognition are generated.

Advancements in CO2 Capture Technologies: A Review of Amine Absorption and Alternative Methods for Post‐Combustion Integration

open access: yesAsia-Pacific Journal of Chemical Engineering, EarlyView.
ABSTRACT Carbon capture technologies are poised to become one of the primary focuses regarding the achievement of net‐zero emissions by the year 2050. In these technologies, particular attention is given to post‐combustion CO2 capture, which is more easily implemented at existing power stations and other industries.
