Porphyrin-Cross-Linked Unimolecular Polyglycerol Nanogels: Confinement-Controlled Metalation and Selective Cu2+ Detection
Abstract Unimolecular nanogels (NGs) based on (hyper)branched cyclic polyglycerols ((h)bcPGs) of two molecular weights (Mn = 8 and 60 kDa) were prepared through intramolecular cross-linking with the tetraboronic acid–functionalized porphyrin, 5,10,15,20-(tetra-4-dihydroxyborylphenyl) porphyrin (TPP-4B) under mildly bas...
