of four diastereoisomers due to (E)- or (Z)-configuration of the C–C double bond and relative syn- or anti-configuration of two stereocenters. The red compounds contain the prototype of the thioindigochromophore. Their double bond configuration can be switched from (E) to (Z) by visible light. Two propargyl-functionalized thiolane monomers were clicked together by para-bis(azidoalkyl)benzene derivatives
