Advantage of the N‐Alkylation Strategy for Retaining the Molecular Planarity for Oligothiophene/Imidazole/1,10‐Phenanthroline‐Based Heterocyclic Semiconducting and Fluorescent Compounds

Abstract: A family of planar oligothiophene/imidazole/1,10-phenanthroline (OTIP)-based heterocyclic, aromatic, semiconducting, and fluorescent compounds with N-substituted alkyl chains (allyl, n-butyl, n-octyl, n-dodecyl, and n-cetyl) have been designed and synthesized. They all have specific N-coordination sites, various donor-acceptor spacers, good molecular planarity, suitable solubility, and high thermal stability. In comparison with conventional double β-alkylation of the thiophene ring, our results reveal that the… Show more

“…There are lots of reports focused on imidazole derivatives ascribe to the electron‐rich imidazole ring possessing extensive pharmacological activities [2–10] . More in recently, small molecules containing phenanthroline and imidazole heterocyclic aromatic rings have also attracted extensively attentions as promising anti‐tumor candidate [11–17] . For example, a series of 2‐(1H‐pyrazol‐4‐yl)‐1H‐imidazole[4,5f][1,10]phenanthrolines have been reported to show great inhibitory activities against lung adenocarcinoma, which may be associated with their interaction with telomeric DNA [18] .…”
