A new group of bioinspired ionicliquids (ILs) based on glycine betaine and natural or synthetic anions was synthesized. The developed synthesis methods enabled the preparation of designed salts with high yields. The melting points for 17 of the 21 betaine-based salts were below 100 °C, allowing them to be classified as ionicliquids. Moreover, the solubilities of the novel salts in water and organic
