Synthetic efforts toward the preparation of rotaxaneprecursorsbased on phenylacetylenemacrocycles (PAM) are described. The aim of this study was to determine the optimal structural parameters to prepare high-molecular-weight rotaxaneprecursors through a strategy involving two Sonogashira couplings to attach bulky blockers on the PAM core. PAMs with different sizes and functions were prepared and
[2.2]Paracyclophane‐based through‐space conjugated oligomers and polymers were prepared, in which poly(p‐arylene–ethynylene) (PAE) units were partially π‐stacked and layered, and their properties in the ground state and excited state were investigated in detail. Electronic interactions among PAE units were effective through at least ten units in the ground state. Photoexcited energy transfer occurred
