We have shown that highly unspecific solution-based Michael addition transforms into highly selective when carried out on a Pt(111) surface. In this way, we are able to synthesize <em>meta<\/em>-polyaniline oligomers starting from a <em>para<\/em>-functionalized precursor, <em>p<\/em>-aminophenol. This unexpected behavior, which is rationalized by a multitechnique approach including STM, nc-AFM, STS, XPS, and DFT calculations, is composed of 3 steps: dehydrogenation of the alcohol groups, partial dehydrogenation of the amino groups, and intermolecular coupling between activated amino groups and carbon atoms at the <em>meta<\/em> position. This reaction pathway opens a door towards the highly directional synthesis of novel nanostructures of interest in the emerging fields of nanomagnetic materials and spintronics.<\/p>\n<p><img loading=\"lazy\" decoding=\"async\" class=\"aligncenter\" src=\"https:\/\/wp.icmm.csic.es\/esisna\/wp-content\/uploads\/sites\/26\/2020\/10\/TOC_adaptado.png\" width=\"520\" height=\"442\"><\/p>\n<p>You can find the work published in open access in:<\/p>\n<p><span style=\"color: #0000ff\"><a style=\"color: #0000ff\" href=\"https:\/\/onlinelibrary.wiley.com\/doi\/10.1002\/anie.202009863\">N.
