摘要

This review outlines recent advances in the Knoevenagel/aldol condensation approach to build up high-crystalline two-dimensional dynamic vinylene-linked covalent organic frameworks promoted by monomer design and reaction condition optimization.

Abstract

Dynamic covalent chemistry (DCC) is a type of reversible chemical reactions under the control of thermodynamics. The reversibility of DCC allows the exchange of reaction components to form thermodynamically stable products. This kind of reaction has been widely incorporated in various research directions

holding an important significance in guiding emerging fields

such as two-dimensional macrocycles

two-dimensional materials and three-dimensional molecular cages. Of them

covalent organic frameworks (COFs)

as a class of high crystalline porous conjugated polymers linked by dynamic covalent bonds exhibit

huge potential application in various fields

such as gas separation

catalysis

sensing

biomedicines

and electronic devices due to their long-range ordered structures

regular pore distribution

high specific surface areas

and excellent molecular material designability. Vinylene-linked COFs feature high chemical stability and outstanding

-electron delocalization

extremely desired for the development of high-performance semiconducting catalysts and device. However

given that the formation reaction of carbon-carbon double bond only exhibited much poorer reversibility than those of the traditional dynamic covalent bonds

it still a big challenge to well-control the preparation of high-quality vinylene-linked COFs. In this review article

we intend to summarize the synthetic strategy approach to 2D vinylene-linked COFs on the basis of the rational design of the key monomers and the optimized reaction conditions for efficiently promoting Knoevenagel/aldol condensation. Then

we exemplified several applications arising from the unique characters of such kinds of COFs. Eventually

the challenges and opportunities of vinylene-linked COFs were also foreseen.
