“…17 In our previous work, a family of 3,8-disubstituted linear 15e,17def,18 and 5,6-fused planar 19 phen-based aromatic heterocyclic compounds with thiophene/oligothiophene, imidazole, pyridine, pyrazine and benzene groups and their transition-metal complexes have been studied, and some of them show temperature-dependent semiconducting and photoresponsive properties. 17d, 18 Recently, some linear bithiazole-centered aromatic heterocyclic compounds with electron-donating TPA and thiophene donors and their Re(I) complexes have been firstly described because of their adjustable electronic properties. 20 As an extensive study, we intend herein to introduce Re(I) ion into the phen-based aromatic heterocyclic ligands with TPA and thiophene donors at different substituted positions of phen.…”
