Molecular quantum ring formed from a pi-conjugated macrocycle
(The University of Nottingham, 2020-10-14)
The electronic structure of a molecular quantum ring (stacks of 40-unit cyclic porphyrin polymers) is characterised via scanning tunnelling microscopy and scanning tunnelling spectroscopy. Our measurements access the ...
Structural characterisation of molecular conformation and the incorporation of adatoms in an on-surface Ullmann-type reaction
(The University of Nottingham, 2020-11-03)
The on-surface synthesis of covalently bonded materials differs from solution-phase synthesis in several respects. The transition from a three-dimensional reaction volume to quasi two-dimensional confinement, as is the ...
