Simply sublime! Samples of monomeric and dimeric zinc porphyrins were sublimed onto a Cu surface under ultrahigh vacuum conditions. Images obtained by scanning tunneling microscopy at room and low temperature (98 K) show features attributed to individual porphyrin molecules with excellent resolution. In the case of the (relatively large) linear dimer shown, two distinct conformations were detected on a surface with low coverage area. R=CH 2 CH 2 COOCH 3 .
