“…Generally, noncovalent interactions refer to hydrogen bonds; − halogen bonds; , ionic bonds; − and weak interactions such as van der Waals, hydrophobic, , aromatic π–stacking interactions, and so forth. , These powerful driving forces lead to diverse interactions between molecules such as hydrogen bonds of the types O–H···O, N–H···O, C–H···N, and C–H···O and other weaker interactions of the types I···I, O···I, N···Cl, C···H, C···C, and so forth . Furthermore, C–H···lp (lone pair), C–H···π, and π···π interactions also act as cohesive forces in the supramolecular assembly of molecules. , Understanding these forces is also important for solid-state materials with desirable properties in supramolecular chemistry. , …”
