AB - An aromatic triphenylene molecule (2,3-diethyl-1,4-dimethoxytriphenylene; TPH) and its regioselectively Cr(CO)(3)-labeled complex (eta(6)-( 1 2,3,4,4a,12b)-tricarbonyl(2,3-diethyl-1,4-dimethoxytriphenylene)chromium(0); alpha-TPHC) were deposited on a Ag(111) surface by vapor deposition. The monolayers were investigated by X-ray photoelectron spectroscopy and scanning tunneling microscopy. Both substances adsorb with the extended pi-system parallel to the surface and form long-range ordered monolayers. The Cr(CO)(3) group of the alpha-TPHC complex is oriented toward the vacuum. Although the footprints of both substances are similar, the additional Cr(CO)(3) group on the alpha-TPHC leads to a lateral order (unit cell) that is significantly different from that of TPH.
