Nematic polymers: hairpins, ringlets and excimer fluorescence
Short liquid crystalline polymers in a nematic environment are very unlikely to cyclise. Hairpins, abrupt chain folds, favour cyclisation. As a result the cyclisation rate constant exhibits a maximum as a function of chain length. The maximum corresponds to a new object, a "ringlet". The rate constant also depends exponentially on temperature. This suggests excimer fluorescence as a probe of co...
متن کاملStatics and dynamics of hairpins in worm-like main chain nematic polymer liquid crystals
2014 We derive some exact results for the statics of solitary defects (« hairpins ») in the conformations of nematic main chain worm-like polymer liquid crystals in which there is both a bending and a nematic contribution to the potential energy. It is shown that for a polymer of finite length in mechanical equilibrium there can exist only a finite number of hairpins and that these are all unst...
متن کاملElongation and fluctuations of semiflexible polymers in a nematic solvent.
We directly visualize single polymers with persistence lengths l(p), ranging from 0.05 to 16 microm, dissolved in the nematic phase of rodlike fd virus. Polymers with a sufficiently large persistence length undergo a coil-rod transition at the isotropic-nematic transition of the background solvent. We quantitatively analyze the transverse fluctuations of the semiflexible polymers and show that ...
متن کاملA rod-spring model for main-chain liquid crystalline polymers containing hairpins
Main-chain liquid crystalline polymers (LCPs) are used to produce strong fibers due to their ability to form highly-ordered orientational states. For sufficiently long chains it is known that loss of entropy in such highly-ordered states is partly recovered by the formation of socalled hairpins or kinks. The presence of hairpins not only modifies the microstructure of LCPs, but it has also been...
متن کاملThermotropic Chiral Nematic Side-chain Polymers
LLE Review, Volume 66 103 Low-Molar-Mass Liquid Crystals Liquid crystals (LC’s) represent a state-of-matter intermediate between a solid crystal and an isotropic liquid. A liquid crystal flows like an ordinary liquid, while other properties, such as optical and dielectric anisotropies, resemble those of a crystalline solid.1 In general, a somewhat rigid and anisomeric molecular shape (e.g., cyl...
