Abstract

Summary: Laser irradiation at 193 nm of gaseous mixtures of carbon disulfide and ethene induces copolymerization of both compounds and affords chemical vapor deposition of conjugated nano‐chained C/S/H polymer, with contributions from C~2~H~4~ and CS~2~ almost unaffected by very different initial ratio of both educts. The polymer structure is interpreted on the basis of X‐ray photoelectron and FTIR spectra as consisting of >CS, >CC<, CH~2~CH~2~, (CC)S~n~C~4−n~, C(CS)S, S(CS)S and CSSC configurations, whose extent is dependent on the irradiation conditions.
