Optical investigation of on-surface synthesized armchair graphene nanoribbons

On-surface synthesized N ¼ 9-armchair graphene nanoribbons (AGNRs) are investigated by Raman spectroscopy and AFM/micro photoluminescence measurements. In order to perform the optical experiments, the AGNR film is transferred on a glass substrate…

Thermodynamics study of the noncovalent functionalization of surfactant suspended graphene nanosheets with porphyrin molecules

We report on the noncovalent functionalization of graphene with hydrophobic tetraphenyl porphyrin (TPP) molecules in micellar aqueous suspensions. We study the thermodynamical parameters of the reaction using optical spectroscopy, and measure its…
