He I and He II photoelectron spectra of all isomeric mono- and diethynylthiophenes were recorded. The electronic structure was analyzed and spectra assigned on the basis of empirical considerations and semiempirical MO calculations. The spectra indicate various interactions taking place between thiophene π and ethynyl π orbitals. The relationship between deduced electronic structure and formation of novel polymer materials is discussed.
