Chemical communication between macromolecules was studied by observing the controlled single chain collapse that ensues the exchange of a metal cross‐linker between two polymer chains. The rhodium (I) organometallic cross‐linker transfer from a low molecular weight collapsed polybutadiene to a larger polymer was followed using size exclusion chromatography. The increased effective molarity in the larger polymer seems to be the driving force for the metal migration. Thus, we demonstrate here a strategy for transferring a molecular signal that induces chain collapse of a polymer chain based on non‐covalent interactions, mimicking biological behaviors reminiscent of signal transductions in proteins.
