We developed a simple method for preparation of well-defined films of X-, T- and anchor-shaped bolaamphiphiles. The compounds were judiciously chosen to investigate the influence of the general molecular structure on the self-assembly properties. Precisely calculated (on the basis of Langmuir π(A) isotherms) volumes of chloroform solutions of the compounds of known concentrations were spread (drop-casted) directly onto the surface of water or silicon wafer. During the solvent evaporation…

Self-Assembly of Gold Nanoparticles into 2D Arrays Induced by Bolaamphiphilic Ligands
We performed synthesis and investigated the self-assembly properties of gold nanoparticles (NPs) with covalently attached bolaamphiphilic ligands (B-AuNPs). The judiciously designed coating rendered…
Langmuir Films of Perfluorinated Fatty Alcohols: Evidence of Spontaneous Formation of Solid Aggregates at Zero Surface Pressure and Very Low Surface Density
TLDR
Simulation results clearly showed that perfluorinated alcohols have an intrinsic tendency to aggregate, even at very low surface density, and the formed domains are highly organized compared to those of hydrogenated alcohols with similar chain length.
Ordered liquids and hydrogels from alkenyl succinic ester terminated bola-amphiphiles for large-scale applications.
TLDR
Both the use of the dimer fatty acid based spacer as well as of ASA head groups open up large-scale applications of ordered liquids (or hydrogels) as a formulation basis for e.g. films, coatings and adhesives.

Aggregation and layering transitions in thin films of X-, T-, and anchor-shaped bolaamphiphiles at the air-water interface.
TLDR
11 compounds from the group of specific surfactants, known as bolaamphiphiles, that exhibit reversible aggregation and, in many cases, transition to well-defined multilayers, which can be considered as a layering transition.

TLDR
A model for the molecular structure of the fibrils which considers the extreme constitution of the bolaamphiphile, which is not driven by hydrogen bonds but solely by hydrophobic interactions of the long alkyl chains is proposed.
