Abstract
Chemoimmunotherapy can boost strong antitumor immune responses by triggering immunogenic cell death (ICD), which highlights a promising prospect in clinical applications. However, current chemoimmunotherapy shows limited efficacy due to the low delivery efficiency and insufficient immunogenicity of available chemotherapeutic drugs. A supramolecular polymeric nanomedicine (Pt-Tu@NP) is herein reported using cucurbit[7]uril-based host-guest recognition and noncovalent self-assembly. Pt-Tu@NPs have excellent biodistribution and strongly evoke the endoplasmic reticulum stress-mediated ICD of tumor cells, triggering potent antitumor immune responses by promoting dendritic cell (DC) maturation and cytotoxic T cell infiltration. The coordinated butyrate promotes a positive feedback regulation between DCs and CD8+ T cells. Pt-Tu@NPs stimulate immune cold tumors into hot ones, working in synergy with an immune checkpoint blockade to effectively suppress tumor growth and metastasis, which suggests a promising approach for cancer chemoimmunotherapy.

Abstract
A new class of macrocycles denoted as "xanthene[n]arenes" was synthesized. In contrast to most other macrocycles, they feature a conformationally restricted bowl shape due to the attached alkyl groups at the linking methylene units. This facilitates the synthesis of cavitands and the self-assembly to molecular capsules via noncovalent interactions. The derivatization potential of the novel macrocycles was demonstrated on the xanthene[3]arene scaffold. Besides a deep cavitand and an oxygen-embedded zigzag hydrocarbon belt[12]arene, a modified macrocycle was synthesized that self-assembles into a hydrogen-bonded tetrameric capsule, demonstrating the potential of xanthene[n]arenes as a new set of macrocyclic building blocks.
