Photoalignment of liquid crystalline polymer with N-benzylideneaniline (NBA) side groups and subsequent in situ exchange achieves polarized fluorescence of oriented N-salicylideneaniline (SA) derivatives. In situ hydrolysis of NBA and c...
<p>A photo-cross-linkable liquid crystalline polymer (PMCB6M) film can be applicable to LC alignment layer. In case of LC alignment, a near surface structure of alignment layer is most important. We investigated three-dimensional molecular orienta...
<p>Supramolecular liquid crystal using the interaction of pyridine-carboxylic acid is known to many. On the other hand, previously, we have reported that the axis-selective anisotropy is generated by irradiating the LPUV light in the thin film of ...
<p>Photoalignment can be applicable to optical information storage, polarization holography, and photoalignment of low-molecular-weight liquid crystals (LCs). To date, several types of photoreactive liquid crystalline polymers (PLCPs) realize an e...
Homeotropically aligned azobenzene liquid-crystalline elastomer (LCE) films were prepared and investigated in terms of the photoinduced bending behavior. Upon irradiation of UV light which induces photoisomerization of the azobebzene moieties, the...
We prepared various chromophores containing hydrogen bonding unit and investigated their change in photoluminescent properties induced by mechanical stimuli. We reported photoluminescent color and lifetime tuning of complex compound of dyes and ac...
In this study, we synthesized new hydrogen-bonding asymmetric luminophores with different site of substitution, and evaluated their optical properties, orientation properties on hydrogen-bonding photo-alignment polymer film by UV-vis absorption sp...
Schiff base compound is well known as liquid crystalline material, and photoisomerization can occur. However, photoreaction of liquid crystalline polymers (LCPs) with schiff base side group have not been investigated. In this presentation, we synt...
We prepared novel polymethacrylates containing phenyl cyano vinyl terthiohene side chain and evaluated their mesomorphic propeties. Additionally, we synthesized oligothiophene with the same structure and explored their alignment behavior on photoa...
A photo-cross-linkable liquid crystalline polymer (PMCB6M) film is applicable to LC alignment layer and it is important to investigate reorientation behavior at the near surface of reoriented PMCB6M film. In this study, reorientation behavior of P...
