Resolution of intramolecular dipoles and push-back effect of individual molecules on a metal surface Open
Molecules consisting of a donor and an acceptor moiety can exhibit large intrinsic dipole moments. Upon deposition on a metal surface, the dipole may be effectively screened and the charge distribution altered due to hybridization with sub…

Aggregation-induced emission leading to two distinct emissive species in the solid-state structure of high-dipole organic chromophores Open
Fluorescence lifetime measurements reveal two emissive species in the solid-state structure of high-dipole chromophores unravelled by high-level quantum-chemical approaches to originate from both monomers and H-type dimers.

In situ functionalization of graphene Open
While the basal plane of graphene is inert, defects in it are centers of chemical activity. An attractive application of such defects is towards controlled functionalization of graphene with foreign molecules. However, the interaction of t…
