<p>Mechanochromic luminescence (MCL) is an isothermal change in photoluminescence in excess of two states, and at least one pathway is induced by mechanical stimuli such as grinding, s hearing, pressing and stretching. This property is expected fo...
<p>Charge transport properties of liquid crystalline semiconductors can be controlled by tuning their aggregation structure and orientational state. In the previous work, we synthesized liquid crystalline oligothiophene based on cyano vinyl terthi...
In this paper, we reported novel liquid-crystalline luminophore that switches its photoluminescent color by mechanically grinding. Mechanochromic luminescence (MCL) is expected for mechanical sensor, cellular imaging, detection of microenvironment...

The cooperative molecular reorientation in methacrylate copolymer films comprised of hexamethylene spacer groups terminated with photoreactive hydrogen (H) bonded 4-oxycinnamic acid (CA) and 4-oxy-4'-methoxyphenylbenzoate (MBe) in their side chain...
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...
