Since the first report of geminal dicationic ionic liquids in 2003 1 , much effort has been devoted to the geminal dicationic ionic liquids because their superior physical properties compared to traditional monocationic ionic liquids 2 . The application as solvents in high-temperature reactions 3 , novel high-temperature lubricants 4,5 , ultrastable separation phases 6 and dye sensitized solar cells 7,8 have been reported.It is well known that the chiral monocationic ionic liquids are attractive due to their potential for asymmetric synthesis 9,10 ,

In article 1900147, Chuanbin Wu, Daojun Liu, Jianfeng Cai and co‐workers design star‐shaped poly(l‐lysine)s as a class of versatile molecular scaffolds for the development of multi‐arm antimicrobial agents. The star‐shaped molecular architecture of poly(l‐lysine)s is characterized by unique advantages such as enhanced cationic charging density and improved proteolytic stability, thus exhibiting high membrane binding, effective membrane‐disruption and unprecedented antimicrobial activity in vitro and in vivo.
