研究目的
To analyse the capabilities of (R)-2-[4”-(trans-4-butylcyclohexyl)-2’-chloro-p-terphenyl-4-oxy) propanoic acid to simultaneously serve as a matrix for inorganic semiconductor nanoparticles (NP), a chiral dopant for liquid crystals, and a chiral ligand stabilizing the surface of CdSe NPs.
研究成果
The synthesized mesogenic-like acid can serve as a liquid crystal matrix, a chiral dopant, and a stabilizer for nanoparticles. Its interactions with nanoparticles and effects on liquid crystal properties are in qualitative agreement with theoretical predictions, though quantitative discrepancies suggest additional factors at play.
研究不足
The quantitative difference in the depression of the transition temperature exceeds theoretical estimates, indicating that the dilution effect alone cannot explain the observed phenomena.
