Recent Advances in Porous Coordination Polymers

Abstract

elements that naturally combined into a fixed morphologies leading to higher order structures with defined porosity and topology (40-42).Crystal Engineering. In addition to metallosupramolecular chemistry, there is also crystal engineering, which contributes to parts of the solid state aspect of supramolecular chemistry. Crystal engineering has also been a vital component for the growing comprehension of coordination polymers. Since, it aims to purposefully create novel compounds though the comprehension of the packing tendencies of various molecules; it can be exploited to engineer coordination materials (43)(44)(45)(46). This field's significance is based on the bulk properties displayed by large complexes, which are fundamentally a consequence of the default arrangements of molecular elements that dictate the specific function of the material or system (47-50). The main idea is that the study of the molecular packing tendencies of a system can then impart an understanding about the macroscopic properties of that system. Moreover, the crystal engineer hopes to properly utilize and understand interactions such as van der Waals forces, hydrogen bonding, π-interaction, coordination bonding, and halogen bonding (51). Considering the depth of the possible interactions in a theoretically engineered complex, there can exist elements of synergy when using each in a simultaneous fashion. With MOFs and PCPs, this precise interaction control in network formation is important to consider for building block components (52).
