Preparation of 7,8-diazaphencyclone and its use in the construction of rigid, space-separated 1,10-phenanthroline donor–acceptor systems: new ligands for metal complexation

Abstract

7,8-Diazaphencyclone 7 is used as a delivery reagent to fuse 1,10-phenanthroline groups onto alkenic centres of rigid spacer molecular racks (molracs); molrac alkenes containing redox-active donor–acceptor chromophores yield molrac diads whose metal complexes, e.g. 26, are suitable for mechanistic studies involving intramolecular electron transfer.
