Diffraction analysis of highly ordered smectic supramolecules of conjugated rodlike polymers

Polarized luminescence from self-assembled, aligned, and cleaved supramolecules of highly ordered rodlike polymers

A hierarchical self-assembly in comb-shaped supramolecules of conjugated rodlike polymers is reported. The supramolecules consist of poly~2,5-pyridinediyl!, acid dopants, and hydrogen bonded alkyl side chains. A thermotropic smectic state with an exceptionally large coherence length is formed without additional solvent. This allows facile overall alignment resulting in high dichroism and polari...

Controlled assembly of rodlike viruses with polymers.

A practical method to assemble rodlike tobacco mosaic virus and bateriophage M13 with polymers was developed, which afforded a 3D core-shell composite with morphological control.

Self-diffusion of rodlike viruses through smectic layers.

We report the direct visualization at the scale of single particles of mass transport between smectic layers, also called permeation, in a suspension of rodlike viruses. Self-diffusion takes place preferentially in the direction normal to the smectic layers, and occurs by quasiquantized steps of one rod length. The diffusion rate corresponds with the rate calculated from the diffusion in the ne...

Smectic ordering in athermal systems of rodlike triblock copolymers.

The phase behavior of the system of parallel rigid triblock copolymers is examined using the second virial density functional theory. The triblock particle consists of two identical infinitely thin hard rods of finite lengths on the opposite ends of one central hard cylinder with nonzero length and diameter. Stability analyses and free energy calculations show that the system of parallel partic...
