Study of Porous Materials Incorporating Boronate Esters
<p> COF-18Å is one type of Covalent Organic Framework (COF) that incorporates self-assembling covalent bonded boronate esters as secondary building units to form a porous material. COF-18Å has the ability to store gases, high surface areas, good thermal stability, but is susceptible to hydrolysis. …

Nanostrutture porfiriniche attraverso il self-assembly: approccio non-covalente e covalente
… quasi basato interamente su forze di natura non-covalente, tuttavia vale la pena considerare che due o più mattoni molecolari possono anche interagire con legami covalenti. Quest’ultimo è il caso del processo di polimerizzazione, in cui il self-assembly covalente porta ad estesi e macroscopici …

Fundamental Understanding of Palladium-Based Catalysts: From Pyrene-Based COFs to Size-Controlled Bimetallic Nanostructures
… free energy and distinct chemical behavior. Covalent organic frameworks (COFs), a class of porous and crystalline materials composed of light elements (H, B, C, N, and O), are attractive supports for SACs due to their designable periodic structures and stable covalent bonding. These …
