Just lately, pyrene-based covalent natural frameworks (PyCOFs) have aroused nice attention-grabbing as a result of the massive planar construction of pyrene unit might successfully improve the interlayer π-π interplay and promote the separation and migration of carriers, considerably bettering the crystallinity and photoelectrical properties of PyCOFs. For the reason that 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 numerous fields equivalent to adsorption/separation, chemical sensing, catalysis, and power storage and so forth. Nevertheless, so far as we all know, the critiques associated to PyCOFs are uncommon, though PyCOFs have been extensively reported to indicate promising purposes. Thus, it’s proper time and vital 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 evaluate will present new insights into PyCOFs that may be explored for extra enticing capabilities or purposes.
