Abstract Precise cancer nanomedicine requires rational molecular instructions of therapeutic agents. Harnessing the structure‐property‐function relationships represents a practical strategy toward smart and effective nanomedicine. A structurally novel hydrogen‐bonded (H‐bonded) supramolecular nanoformulation generated by orthogonal self‐sorting assembly chemo‐prodrug (FPtF) phototherapeutics (BPeB) is here reported, to reach an autonomous with improved anti‐tumor efficacy combining chemo/phototherapy (CT/PT). The high‐fidelity H‐bonding modularity from privileged heterocomplementary diaminopyridine/5‐fluorouracil (DAP/FU) Hamilton wedge/barbiturate (HW/Ba) pairs, respectively enable precise spatial control binding interactions FPtF BPeB, in turn allowing process specific “mix‐and‐match” capability. To directly stimulate phototherapy BPeB via near‐infrared (NIR) light, spectral matched upconversion nanoparticles (UCNPs, β‐NaYF 4 :Yb,Er) are encapsulated simultaneously. As result, polymeric nanomicelles, i.e., F/B/U@PHDO, readily fabricated. Moreover, distinct association constant (Ka) DAP/FU (≈10 2 M −1 ) HW/Ba 4‐5 pairs reflect different strengths stabilities H‐bonds, thus endowing programmable dissociation, accompanied release through pH/thermal‐stimuli. Therapeutic regime appreciated outcomes ultimately accomplished combined CT/PT. opportunities offered design anticipated point new paradigm for therapy.
