Cross-linkable, phosphobetaine-based, zwitterionic amphiphiles that form lyotropic bicontinuous cubic phases

https://doi.org/10.1039/d3sm00269a

Bodkin, Lauren N ; Krajnak, Zachary A ; Dong, Ruiqi ; Osuji, Chinedum O ; Gin, Douglas L ( May 2023 , Soft Matter)

Two new, cross-linkable, phosphobetaine zwitterionic amphiphiles were found to form a type II bicontinuous cubic (Q_II) phase with aq. NH₄Cl. Upon polymerization, they form 3D-nanoporous membrane materials that are not susceptible to ion exchange.

Stable cross-linked lyotropic gyroid mesophases from single-head/single-tail cross-linkable monomers

https://doi.org/10.1039/D1CC04211D

Imran, Omar Q. ; Li, Patrick ; Kim, Na Kyung ; Gin, Douglas L. ; Osuji, Chinedum O. ( October 2021 , Chemical Communications)

A single-head/single-tail surfactant with a polymerizable group at each end is presented as a new simplified motif for intrinsically cross-linkable, gyroid-phase lyotropic mesogens. The resulting nanoporous polymer networks exhibit excellent structural stability in various solvents and are capable of molecular size discrimination.
