Abstract:
Two-dimensional structures in water were self-assembled from rigid and curved amphiphiles with very low molecular weight (MW < 500 Da). The amphiphiles contain a bisnaphthalene core. Their structures have been characterized using 1H NMR spectroscopy, SEM, TEM, AFM, and DLS. The driving force was mainly attributed to hydrophobic effects.

Molecular Weight of Step-Growth Polymers
As the step-growth polymerization involves step-wise condensation of monomers, the molecular weight also builds up eventually. Consequently, high molecular weight polymers are obtained at the late stages of the polymerization, where 99% of monomers have been consumed.
