CuCl₂, 2,7-bis(bromomethyl)naphthalene, sodium sulphate and potassium carbonate were purchased from TCI Europe and used without further purification. Bis(2-pyridylmethyl)amine was synthesized as previously reported (35 (link)). Deuterated chloroform was obtained from Apollo Scientific. ¹H NMR spectra were recorded on Jeol ECX-400 and Varian 500 AR spectrometers at room temperature and all chemical shifts are relative to the residual solvent peak. ESI Mass Spectra were recorded on a Waters LCT Premier XE Spectrometer in positive mode. Microanalysis (C, H and N) was carried out using a Perkin Elmer 2400 series II analyzer. UV–Vis spectra were recorded on a Jasco UV–Vis spectrophotometer in phosphate buffer (pH 6.8). Emission experiments were conducted on a Shimadzu RF-5301 spectrofluorometer at room temperature. Thermal melting analysis was conducted on an Agilent Cary 100 dual beam spectrophotometer equipped with a 6 × 6 Peltier multicell system with temperature controller. Circular dichroism spectra were recorded on an Applied PhotoPhysics Chirascan Plus. Fluorescence spectra were recorded on a Perkin Elmer LC55. Calf thymus DNA was purchased from Invitrogen (15633019) while DNA from salmon testes (D1626) and synthetic alternating co-polymers (poly[d(A-T)₂] (P0883) and poly[d(G-C)₂] (P9389)) were obtained from Sigma Aldrich Ireland.
