Iodination of 5,15-diphenylporphyrin followed by metallation and palladium(0) catalysed coupling with monosubstituted acetylenes gives zinc(II)-10-(2-substituted-alkynyl)-5,15-diphenylporphyrins.

The controlled attachment of chromophores to metal or semiconducting surfaces is a prerequisite for the construction of photonic devices and artificial surface-based light-harvesting systems. We present an approach to mount porphyrins in orderedmonolayers on Au(111) by self-assembly and verify it, employing STM, absorption spectroscopy, and quantum chemical calculations. The usual adsorption geometry
