Phenylacrylonitrile-bridging triphenylene dimers: the columnar liquid crystals with high fluorescence in both solid state and solution

Tetrahydro[5]helicene-based imide dyes with intense fluorescence in both solution and solid state.

A new kind of tetrahydro[5]helicene-based imide dyes with intense fluorescence and large Stokes shifts in both solution and solid state were developed and theoretically investigated.

Dielectric Investigations on Ferroelectric Columnar Liquid Crystals

Stability and numerical solution of time variant linear systems with delay in both the state and control

In this paper, stability for uncertain time variant linear systems with time delay is studied. A new sufficient condition for delay-dependent systems is given in matrix inequality form which depends on the range of delay. Then, we introduce a new direct computational method to solve delay systems. This method consists of reducing the delay problem to a set of algebraic equations by first expand...

Surfactant-Stabilized Single-Walled Carbon Nanotubes Using Triphenylene Derivatives Remain Individually Dispersion in Both Liquid and Dried Solid States

An easy and simple preparation method for individually dispersed single-walled carbon nanotubes (SWNTs) in both liquid and dried solid states was developed using triphenylene derivatives. Furthermore, highly concentrated solution of SWNTs (0.7-0.8 %) was successfully prepared, and also the SWNTs were dispersed well after the addition of methanol (up to 70 %) for a long time. These properties (r...

The Saint-Venant principle for columnar discotic liquid crystals

2014 We compute the high frequency elastic distortion of a columnar discotic single crystal submitted to a longitudinal dilation. The ends of the columns are assumed to be clamped and anchored perpendicularly to two infinitely rigid glass plates, on a width L. The local strain close to the plates relaxes to the homogeneous distortion of an unclamped sample on a characteristic length £ ~ (Lm)1/2...
