Six novel di-substituted phenanthroline derivatives 5a–7a and 3b–5b have been prepared, and their binding interactions with human telomeric (h-telo) and promoter (c-kit2 and c-myc) G-quadruplex DNAs were investigated. All the compounds are potent stabilisers of the G-quadruplexstructures and compounds 3b, 4b, and 5b exhibit high G-quadruplex DNA selectivity over duplex DNA. The binding affinities
