Herein, we introduce a novel on-surface synthesis of coordination polymers with quinoidal ligands under ultra-high vacuum conditions, which enables formation of flexible coordination polymers with lengths up to hundreds of nanometers. Moreover, this procedure allows the incorporation of different transition-metal atoms with four- (M = Cr, Fe, Ni, Co) or two-fold (M = Cu) coordination. Remarkably, the two-fold coordination mode revealed the formation of wires constituted by (electronically) independent 12-membered antiaromatic macrocycles linked together through two C-C single bonds.<\/p>\n<p><img decoding=\"async\" loading=\"lazy\" class=\"aligncenter size-full wp-image-8093\" src=\"http:\/\/www.cinam.univ-mrs.fr\/cinam\/wp-content\/uploads\/2021\/01\/Coordination-wires.jpg\" alt=\"\" width=\"430\" height=\"388\" srcset=\"https:\/\/www.cinam.univ-mrs.fr\/cinam\/wp-content\/uploads\/2021\/01\/Coordination-wires.jpg 430w, https:\/\/www.cinam.univ-mrs.fr\/cinam\/wp-content\/uploads\/2021\/01\/Coordination-wires-300x271.jpg 300w\" sizes=\"(max-width: 430px) 100vw, 430px\" \/><\/p>\n<p>Reference: <span style=\"text-decoration: line-through\"><br \/>\n<\/span>V.
