AI Article Synopsis

  • A Co(ii)-based metallo-polymer (Co-tpy-L) is created using a method called solvent-solvent interfacial polymerization.
  • The resulting thin film shows an electrochromic property, changing color from transmissive to blackish green.
  • This electrochromism effectively covers visible and near-infrared (NIR) light regions and operates within a moderate voltage range from -1.4 to 0 V.

Article Abstract

Herein, a Co(ii)-based metallo-polymer (Co-tpy-L) with a three armed non-conjugated terpyridine ligand is synthesized using solvent-solvent interfacial polymerization. The thin film exhibits durable transmissive-to-blackish green electrochromism, selectively covering both the visible and NIR regions with a moderate voltage range of -1.4 to 0 V.
