Supramolecular polymers with facile and versatile architectures via noncovalent connection present great potential in biological fields. Herein, a linear alternating supramolecular polymer is constructed via host-guest inclusion interaction between cyclodextrin-dimer (CD2) and bifunctional adamantane-conjugated porphyrin (TPP-Ad2). The supramolecular alternating structure of CD/TPP could not only suppress the aggregation of PSs to im-prove the photophysical properties because of the steric hindrance, but also enhance the water solubili-ty of PSs induced from cyclodextrin moieties. The nanoplatform obtained by this linear alternating su-pramolecular polymer (TPP-Ad2/CD2) presents significantly enhanced PDT efficacy, providing a promising path for PDT.
