Tetraphenylsilane-based oligo(azomethine)s containing 3,4-ethylenedioxythiophene units along their backbone: Optical, electronic, thermal properties and computational simulations

Three new silylated-oligo(azomethine)s with TPS and EDOT units in their structure and moderated molecular weights are reported. The materials showed high solubility in DCM, THF, and chloroform, and high thermal stability. Electronic experiments evidenced wide-band-gaps materials (2.73–2.83 eV). DFT and TDDFT calculations were performed for pentamers obtaining good agreements with the experiment UV–vis parameters and band-gaps values.
