Living polymers composed of non-covalently bonded building blocks with weak backbone flexibility may self-assemble into thermoresponsive lyotropic liquid crystals. We demonstrate that the reversible polymer assembly and phase behavior can be controlled by the addition of (non-adsorbing) rigid colloidal discs which act as an entropic reorienting “template” onto the supramolecular polymers. Using a particle-based second-virial theory that correlates the various entropies associated with the…

Polymeric Nematics of Associating Rods: Phase Behavior, Chiral Propagation, and Elasticity

Rod-shaped colloids with attractive tips can form linear aggregates that may subsequently undergo hierarchical self-assembly into nematic fluids. Inspired by recent modeling efforts on chromonic

Self-assembly, condensation, and order in aqueous lyotropic chromonic liquid crystals crowded with additives

Dense multicomponent systems with macromolecules and small solutes attract a broad research interest as they mimic the molecularly crowded cellular interiors. The additives can condense and align the

Phase stability of colloidal spheres mixed with supramolecular rod‐like polymers

Mixtures of colloids and supramolecular polymers exhibit stimuli-responsive phase behavior. In previous work (Peters and Tuinier, Physica A 510, 233 [2018]) the polymers were treated as fully

Hybrid molecular-colloidal liquid crystals

Self-assembly of colloidal and molecular rods yields orthorhombic nematics with switchable biaxial optical properties, in which like-sized rods are roughly parallel to each other and the molecular ordering direction is orthogonal to that of colloid rods.

Chain self-assembly and phase transitions in semiflexible polymer systems

We present a phenomenological theory of the interplay between linear self-assembly, isotropic attractions, and orientation-dependent repulsions in determining the phase behavior of particles that

Liquid crystal phase transitions in suspensions of polydisperse plate-like particles

A suspension of plate-like colloids that shows isotropic, nematic and columnar phases on increasing the particle concentration is described, finding that the columnar two-dimensional crystal persists for a polydispersity of up to 25%, with a cross-over to smectic-like ordering at very high particle concentrations.

Unveiling the subtle rules that control the buildup of macroscopic chirality starting from chiral molecular elements is a challenge for theory and computations. In this context, a remarkable
