For the first time, hybrid materials with long-range order (lamellar and even 2D hexagonal) were obtained during hydrolysis–polycondensation of α,ω-bis(trimethoxysilyl)alkanes thanks to hydrophobic van-der-Waals type interactions using highly hydrophilic conditions, the nanostructure depending mainly on the alkylene chain lengths.
The synthesis and physicochemical characterisation of a series of polymethylene-1,omega-bis(phosphocholines) with even-numbered chain lengths between 22 and 32 carbon atoms is described. Two new synthetic strategies for the preparation of long-chain 1,omega-diols as hydrocarbon building blocks are presented. The temperature-dependent self-assembly of the single-chain bolaamphiphiles was investigated
