Materials and Methods. NMR spectra were recorded on a Bruker DPX 300, or AV 500 spectrometer at 25 ºC, and the chemical shifts are reported in parts per million using the solvent as reference. The splitting patterns are designated as follows: s = singlet, d = doublet, m = multiplet, bs= broad signal, and the assignments are Napht (naphthalene), and ph (benzene). Mass spectra were recorded by means of MALDI-TOF and FAB/IE techniques with Bruker Reflex 2 and FAB/IE MAT95 XP Thermofisher mass

... rometers respectively. Melting points were collected in a Nikon eclipse 80i microscope coupled with a Linkam heating plate. Elemental analyses were performed on a Perkin-Elmer EA 2400. UV-Vis spectra were recorded in a Varian Cary 50 spectrometer. FTIR spectra were carried out in a Shimadzu FTIR 8300 spectrophotometer. Optical measurements in solution were carried out in 1 cm cuvettes with Merck Uvasol-grade solvents. Absorption spectra were recorded on a Perkin-Elmer Lambda 19 spectrometer, and corrected fluorescence spectra were recorded on a Perkin-Elmer LS 55 fluorescence spectrometer. TGA and DSC measurements were performed at a heating rate of 10 ºC/min under nitrogen flow on a TA Instruments SDT Q600 and a METTLER TOLEDO DSC822 respectively. Cyclic voltammetry experiments were performed with a computer controlled Autolab Electronic Supplementary Material (ESI) for Chemical Communications This journal is
