Summary:

In this contribution we describe the synthesis and investigation of Au NPs functionalized with organic mesogenic groups which self-assemble into liquid crystalline phases. A nematic mesogenic liquid crystalline laterally reacts with functionalized gold via a siloxane group using Karstedt’s catalyst. Compared to earlier work where NPs were in the size of 1.5- 2.5 nm, we report here on larger than 5 nm sized particles.
