WebThiol-PEG12-acid is a PEG linker containing a thiol group and a terminal carboxylic acid. The hydrophilic PEG spacer increases solubility in aqueous media. The thiol group … WebHere we demonstrate photocontrol of transmembrane transport and electric potential using bis(thio)ureas derived from stiff-stilbene. UV−vis and1H NMR spectroscopy are used to monitor E−Z photoisomerization of these bis(thio)ureas and1H NMR titrations reveal stronger binding of chloride to the (Z)-form than to the (E)-form.
