Invited for the cover of this issue is the group of Emmanuel Terazzi at the University of Geneva, Switzerland. The cover image shows how single-stranded dinuclear lanthanide helicates (green) survive immersion into a drop of less polar solvent (e.g. CH2Cl2) and their eventual self-organization into a liquid-crystalline material.
瑞士日内瓦大学的 Emmanuel Terazzi 小组受邀为本期封面。封面图片展示了单链双核
镧系元素螺旋体(绿色)如何在浸入一滴极性较小的溶剂(例如
CH2Cl2)中幸存下来,并最终自组织成液晶材料。
