Abstract Cholesteryl trimeric phenylene vinylene (ChoI-TPV) has been synthesized and characterized. The self- assembly behaviors of ChoI-TPV in THF/H20 system at different water content (water content: 40% and 80%) and different solute concentration (solute concentration: 1.0 ×10^-5 mol/L and saturated concentration) were studied using UV-vis spectrophotometry, photoluminescence spectrophotometry, and circular dichroism spectroscopy. Based on an analysis of the UV-vis and photoluminescence spectra, Chol-TPV shows the typical H-type aggregation at saturated concentration in 80% aqueous THF. However, ChoI-TPV shows the non-typical H-type aggregation under other conditions. The circular dichroism signal suggests that the Chol-TPV exists in the right handed helical architectures with high water content at a concentration of 1.0 × 10^-5 mol/L, and a helix inversion was found at saturated concentration.

Cholesteryl trimeric phenylene vinylene (ChoI-TPV) has been synthesized and characterized. The self- assembly behaviors of ChoI-TPV in THF/H20 system at different water content (water content: 40% and 80%) and different solute concentration (solute concentration: 1.0 ×10^-5 mol/L and saturated concentration) were studied using UV-vis spectrophotometry, photoluminescence spectrophotometry, and circular dichroism spectroscopy. Based on an analysis of the UV-vis and photoluminescence spectra, Chol-TPV shows the typical H-type aggregation at saturated concentration in 80% aqueous THF. However, ChoI-TPV shows the non-typical H-type aggregation under other conditions. The circular dichroism signal suggests that the Chol-TPV exists in the right handed helical architectures with high water content at a concentration of 1.0 × 10^-5 mol/L, and a helix inversion was found at saturated concentration.
