  • Publication number: 20220283152
    Abstract: Phenyl rings provide a robust scaffold for molecular design, given the limited number of ring carbon atoms and the fixed geometry in between. Alternating groups in hexasubstituted benzenes may be directed toward opposite faces of the phenyl ring, such that orthogonal reactive groups are directed toward the opposite faces for promoting both surface attachment and introduction of functionalities suitable for promoting analyte detection. Hexasubstituted benzenes capable of covalent bonding to a surface and having functionalities capable of promoting detection of one or more analytes in fluids may be realized. An analytical response of the hexasubstituted benzenes or a change thereof may be correlated to an amount of at least one analyte present in a fluid, including both single- and multi-phase complex fluids.

  • Publication number: 20220144733
    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.
