A series of single-layer phthalocyanine-based covalent-organic frameworks (COFs) are shown to possess tunable delocalized electronic states which are attractive for optoelectronic applications.

<p>The electron delocalization in the single-layer phthalocyanine-based covalent-organic frameworks (COFs) makes them attractive materials for semiconducting and optoelectronic applications. Moreover, their electronic and charge carrier transporting performance can be engineered via rationally designing the building units.</p>
