title: A convenient method for the synthesis of alpha-ethynylphospholes and modulation of their pi-conjugated systems.
abstract: Mind the (narrow) gap: Alpha-ethynylphospholes generated in situ from the corresponding silyl-capped precursors were converted into a series of alpha-(arylethynyl) phospholes bearing functional substituents as well as an alpha,alpha'-linked terphosphole (see scheme). The terphosphole has a narrow HOMO-LUMO gap owing to efficient pi conjugation over the three phosphole rings.
