védésThursday, 22 June 2023, 10:00, KFKI Campus, Bldg. 1, 2nd floor, 
Conference RoomSexithiophene molecules are encapsulated using two 
encapsulation methods: one usually used in the literature which requires high 
temperature, and another using supercritical carbon dioxide at low 
temperature. It is shown how polymerization occurs during the encapsulation 
using the high temperature method. Additionally, as this precursor has 
similar characteristics to graphene nanoribbon (GNR) precursors, their 
synthesis is attempted from this molecule. However, it could be evidenced 
that this molecule does not form GNRs. The synthesis of graphene nanoribbons 
is reported from a new precursor 1,2,4-trichlorobenzene. This precursor is a 
liquid and has several advantages for encapsulation and product formation. 
Graphene nanoribbons several nanometers long are prepared inside 
single-walled carbon nanotubes and the 6-armchair graphene nanoribbon is 
detected. The above synthesis is also performed in boron nitride nanotubes 
where the nanoribbon formation has not been as successful so far as inside 
carbon nanotubes. The significance of producing graphene nanoribbons using 
boron nitride nanotubes lies in the transparent nature of these tubes which, 
contrary to carbon nanotubes, allows obtaining information of the reaction 
products in a wide optical range. Join Zoom
