Just lately, pyrene-based covalent natural frameworks (PyCOFs) have aroused nice attention-grabbing as a result of the big planar construction of pyrene unit may successfully improve the interlayer π-π interplay and promote the separation and migration of carriers, considerably enhancing the crystallinity and photoelectrical properties of PyCOFs. Because the first PyCOF-containing boroxate linkage was reported in 2008 by Yaghi group, many PyCOFs with completely different sorts of linkages have been reported, exhibiting nice potential purposes in several fields equivalent to adsorption/separation, chemical sensing, catalysis, and vitality storage and many others. Nevertheless, so far as we all know, the evaluations associated to PyCOFs are uncommon, though PyCOFs have been broadly reported to point out promising purposes. Thus, it’s proper time and necessary for us to systematically summarize the analysis advance in PyCOFs, together with the synthesis with completely different linkages and purposes. Furthermore, the prospects and obstacles going through the event of PyCOFs are mentioned. We hope that this overview will present new insights into PyCOFs that may be explored for extra enticing capabilities or purposes.
