## Abstract Novel acetylene monomers containing cholesteryl groups, __N__‐cholesteryloxycarbonyl‐2‐ethynylcarbazole (**1**) and cholesteryl __N__‐propargylcarbamate (**2**) were synthesized and polymerized with an Rh catalyst to give the corresponding polymers [poly(**1)** and poly(**2**)] with $\o
## Abstract Three diacetylene macromonomers based on oligopeptide‐polymer conjugates were designed to self‐organize into uniform supramolecular polymers which exhibited multiple‐helical superstructures constituted from a defined, finite number of laminated single __β__‐sheet tapes. These supramolec
