Abstract

Covalent Organic Frameworks are a kind of novel porous crystalline materials and have exhibited considerable potential for many applications, such as gas adsorption and storage, photoconduction, sensing, heterogeneous catalyst, charge transport and separation, photovoltaic devices, energy storage, drug delivery, hydrogen generation and proton conduction, etc. However, the limits on monomers and synthetic reactions for the preparation of COFs have impeded further advances in this emerging field. To advance this emerging field it is important to expand the scope of building blocks and the types of reactions. This motivated us to explore the possibility of constructing functional COFs with novel π systems and explore novel reactions for the construction of COFs with new linkages.

Porphyrins are largeπ-electronic macrocycles with broad absorbance and have been widely employed for the construction of functional materials. However, the structural control and the ordering of molecular alignment of porphyrin derivatives in a multi-porphyrin system is difficult because of their low solubilities and strong interactions. Pyrene is another well knownπ-electronic building block has been widely utilized in the synthesis of materials with light-emitting, long lifectime, or high quantum yield properties. Construction of pyrene based COFs and explore the fluorescence property can extend the family of COFs with light-emitting functions.

This topic consists of the design and synthesis ofπ-electronic covalent organic frameworks, with an emphasis on the development of newπ-electronic molecular frameworks and extending the reaction for the formation of frameworks.1-6
