Figure 3

Phase transitions of a library of 57 room-temperature ionic liquids upon mixing with water (1:2, w/w) at temperatures between 2 °C and 90 °C: (A) ionic liquids a1–a25, (B) ionic liquids b1–b25, (C) ionic liquids a1–a25 along with 3 additional ionic liquids having branched sidechains a26–a28, and (D) ionic liquids b1–b25 along with 4 additional ionic liquids with branched sidechains b26–b29. Phase transition results shown in red and blue indicate entirely homogeneous (one-phase) and heterogeneous (two-phase) solutions, respectively, between 2 °C and 90 °C. In this library, two ionic liquids show phase transitions: b26 ([Bu-i-Hex-C2OH-tr][OTMBS]; Tc = 17 °C), and b27 ([Pent-i-Pent-C2OH-tr][OTMBS]; Tc = 8 °C).
