Abstract: Phenyl rings provide a robust scaffold for molecular design, given the limited number of ring carbon atoms and the fixed geometry in between. However, it can be difficult to form highly substituted phenyl rings suitable for covalent attachment of multiple moieties thereto. Moreover, binding phenyl rings to a surface in a fixed geometry may be difficult. Hexasubstituted benzenes having certain structural features may alleviate the foregoing difficulties by providing versatile groups for further functionalization and surface attachment. Such hexasubstituted benzenes may have a structure of in which each X is independently Cl, Br or N3, and each Z is independently —CH(Br)CH3, —CH(N3)CH3, —CH?CH2, —CH2CH3, —CH2CH2SiR?3 (R?=hydrocarbyl), or Alternating groups in the hexasubstituted benzenes may be directed toward opposite faces of the phenyl ring, such that orthogonal reactive groups are directed toward the opposite faces. Certain groups may facilitate surface attachment of the hexasubstituted benzenes.

Abstract: Macroparticulates may be formed through at least partial self-assembly by reacting an epoxide-containing (meth)acrylic polymer or copolymer with a compound bearing a nitrogen nucleophile. An internal cavity may be formed when functionalizing the (meth)acrylic polymer or copolymer in the presence of a hindered amine base. When appropriately functionalized, the macroparticulates may be used to sequester a contaminant from a substance in need of contaminant remediation, such as produced water or flowback water from a wellbore job site. Reclaimed water obtained from the macroparticulates may be utilized to form a treatment fluid. The macroparticulates may be located within a continuous flow line, particularly within a removable cartridge, to promote removal of at least one contaminant from a substance in need of contaminant remediation.
