含氟烷基偶氮苯实现光切换固-液状态，用于时空可控润滑与液体运动操控
Fluoroalkylated Azobenzenes with Photoswitchable Solid–Liquid States Enabling Spatiotemporally Controlled Lubrication for Liquid Motion Manipulation
AI 导读
研究团队设计出含氟烷基偶氮苯，兼具低表面张力与光诱导可逆固-液转变，其 trans 态为不润滑固体，光照转为 cis 态后成为液体润滑剂。作者将这类分子灌注到微结构基底中，制得可在液体钉扎态与滑移态之间光切换的表面，从而按需构建和重构引导通道，控制多种液体的滑动。该工作提出以光诱导可逆固-液转变实现时空可控润滑的新机制，面向微流控、微反应器与自适应表面。
推荐理由
作者设计出固态下可发生 trans-cis 光异构的含氟烷基偶氮苯，为光控润滑表面提供了新的分子设计思路。
创新点
以往含氟烷基链通常抑制固态光异构，作者通过调控分子与晶体结构，使含氟烷基偶氮苯在固态下仍能高效进行 trans-cis 光异构，从而把低表面张力与光诱导固-液转变结合在同一体系中。
