Abstract

Tune it with light! Self-assembled monolayers on gold based on a chemisorbed novel azobenzene derivative with a perfluorinated terminal phenyl ring are prepared. The modified substrate shows a significant work function increase compared to the bare metal. The photo-conversion between trans and cis isomers chemisorbed on the surface shows great perspectives for being an accessible route to tune the gold properties by means of light.

摘要

用光来调节！基于化学吸附在具有全氟末端苯基环的新型偶氮苯衍生物上的金的自组装单层被制备。与裸金属相比，修饰后的基底的功函数显著增加。化学吸附在表面上的顺式和反式异构体之间的光转换为通过光来调节金的性质提供了一种可行的途径。
