不同的纳米颗粒表层允许独特的功能。我们开发了一种在金纳米棒表面通过π堆积形成固体层的四氰喹诺二甲烷涂层方法。考察了反应时间、老化时间和表面活性剂浓度对其反应机理的影响。我们的方法可以推广到不同的纳米颗粒形状和晶体面。
Various nanoparticle surface layers allow unique functionalities. We developed a coating method with tetracyanoquinodimethane that forms solid layers through π stacking on gold nanorod surfaces. Its reaction mechanism was investigated with reaction time, aging time and surfactant concentration. Our method could be generalizable to different nanoparticle shapes and crystal facets.
