ABSTRACT
A series of symmetrical tetraesters with a tetrahydroxybenzene core, semi-flexible oligobenzoate arms and one to three peripheral aliphatic chains per arm have been synthesised to study the influence of space-filling and nanosegregation in the mesophases. All compounds were comprehensively investigated by polarised optical microscopy, differential scanning calorimetry and X-ray scattering techniques. Modelling based on this data revealed that the competition of space-filling and nanosegregation furnishes a number of columnar and lamellar phases. Various folded molecular structures are the basic mesogenic building blocks. In contrast to earlier predictions, the tetraesters fold to lath-, cross-, cone- and bowl-like conformers depending on the type of the mesophase.
