The bowl-shaped, 3-fold interlinked porphyrin dimer <b>2</b> was obtained in respectable yields during macrocyclization
attempts.
Its bicyclic structure, consisting of a macrocycle made of a pair
of acetylene interlinked tetraphenylporphyrins which are additionally
linked by a C–C bond interlinking two pyrrole subunits, has
been confirmed spectroscopically (2D-NMR, UV/vis, HR-MALDI-ToF MS).
Late-stage functionalization provided the structural analogue <b>1</b> with acetyl-protected terminal thiol anchor groups enabling
single molecule transport investigations in a mechanically controlled
break junction experiment. The formation of single-molecule junctions
was observed, displaying large variations in the observed conductance
values pointing at a rich diversity in the molecular junctions.
