Cholesteryl trimeric phenylene vinylene(Chol-TPV) has been synthesized and characterized. The selfassembly behaviors of Chol-TPV in THF/H2 O system at different water content(water content: 40% and 80%) and different solute concentration(solute concentration: 1.0 10 5mol/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, Chol-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 5mol/L, and a helix inversion was found at saturated concentration.
