An efficient synthesis of unprecedented fused extended-tetrathiafulvalene-dipyridoquinoxaline (exTTF-dpq) dyad is described through the Horner-Wardsworth-Emmons olefination methodology from the dipyrido[3,2-a:2%26apos;,3%26apos;-c]-benzo [3,4]phenazine-11,16-quinone (NqPhen) ligand starting material. This exTTF-dpq dyad is demonstrated to act as a dual redox and colorimetric sensor for cations exploiting the proximity between the redox tetrathiafulvalene and the optical phenanthroline detecting sites. Its ability for sensing cations from the d-group metal transitions (Fe2+, Ni2+, and Zn2+) and also with varied cations such as Ca2+ and Pb2+ is presented.
