Designed synthesis of stable light-emitting two-dimensional sp² carbon-conjugated covalent organic frameworks.

ABSTRACT: Covalent organic frameworks enable the topological connection of organic chromophores into π lattices, making them attractive for creating light-emitting polymers that are predesignable for both the primary- and high-order structures. However, owing to linkages, covalent organic frameworks are either unstable or poor luminescent, leaving the practical synthesis of stable light-emitting frameworks challenging. Here, we report the designed synthesis of sp² carbon-conjugated frameworks that combine stability with light-emitting activity. The C=C linkages topologically connect pyrene knots and arylyenevinylene linkers into two-dimensional all sp² carbon lattices that are designed to be π conjugated along both the x and y directions and develop layer structures, creating e
