Figure 7

LCST Phase transitions of a library of 52 ionic liquids upon mixing with water (1:2, w/w) at temperatures between 2 °C and 90 °C: (A) ionic liquids c1–c25, (B) ionic liquids d1–d25, (C) ionic liquids c1–c25 along with one additional ionic liquid c26 having an isopentyl sidechain, and (D) ionic liquids d1–d25 along with one additional ionic liquid d26 with an isobutyl sidechain. In this library, 8 ionic liquids in total show phase transitions: c10 ([Bu-Oct-C3OH-tr][OTs]; Tc = 12 °C), c14 ([Pent-Hex-C3OH-tr][OTs]; Tc = 14 °C), c22 ([Oct-Bu-C3OH-tr][OTs]; Tc = 13 °C), c26 ([Hex-i-Pent-C3OH-tr][OTs]; Tc = 25 °C), d9 ([Bu-Hex-C3OH-tr][OTMBS]; Tc = 56 °C), d13 ([Pent-Pent-C3OH-tr][OTMBS]; Tc = 24 °C), d17 ([Hex-Bu-C3OH-tr][OTMBS]; Tc = 25 °C), and d26 ([Oct-i-Bu-C3OH-tr][OTMBS]; Tc = 7 °C).
