Tetrakis-(4-thiyphenyl)methane: Origin of a Reversible 3D-Homopolymer



The efficient syntheses of tetrakis(thiophenol)methane and of a new poly(disulfide) hyper-crosslinked polymer based on the former monomer are described. Controlled de-polymerization as well as surface post-functionalization are successfully conducted on this novel material. Direct prove of post-functionalization is obtained through solid-state fluorescence emission spectroscopy, and the number of unreacted thiol-functions on the surface of the polymeric material is indirectly quantified by de-polymerization of the post-functionalized material.
