Abstract
Metal coordination assemblies of the symmetric bi-functional 4,4-di-(1,4-buta-1,3-diynyl)-benzoic acid are investigated by scanning tunnelling microscopy on metal surfaces. The formation of long-range ordered, short-range disordered and random phases depends on the competition between the convergent and divergent coordination motifs of the individual functional groups and is crucially influenced by the substrate.
Článek popisuje ja lze pomocí volby substrátu selektivně aktivovat alkynylovo skupinu a její ochotu tvořit koordinační vazby s atomy niklu. Výsledkem jsou zcela rozdílné dvourozměrné koordinašní sítě vykazující buď vysokou míru uspořádanosti nebo naopak náhodnou strukturu.
