Research on the properties of heterocyclopentadienes has been conducted over the past 50 years, and this class of molecules has recently been employed in the conductive polymer layer of some organic light-emitting diodes (OLEDs). Heterocyclopentadienes containing metals, also known as metalloles, have demonstrated excellent electron transport abilities which stimulated their use in this way. Through altering the metal contained in the metallole, the band gap of these molecules can then be tuned. Metalloles were synthesized containing group 14 metals. These compounds were characterized by 1H NMR spectroscopy and X-Ray crystallography if applicable. The replacement of the metal contained within the molecule allows for the properties to be altered while the substituents stay the same. These molecules can then be altered to be used as monomers for poly-metallole synthesis.
