  abstract  = {Macrocycles with quaterthiophene subunits were obtained by cyclooligomerization by direct oxidative coupling of unsubstituted dithiophene moieties. The rings were closed with high selectivity by an \&\#945;,\&\#946;\&\#8242;-connection of the thiophenes as proven by NMR spectroscopy. The reaction of the precursor with terthiophene moieties yielded the symmetric \&\#945;,\&\#945;\&\#8242;-linked macrocycle in low yield together with various differently connected isomers. Blocking of the \&\#946;-position of the half-rings yielded selectively the \&\#945;,\&\#945;\&\#8242;-linked macrocycle. Selected cyclothiophenes were investigated by scanning tunneling microscopy, which displayed the formation of highly ordered 2D crystalline monolayers.},
