- W1991401250 abstract "The coordination chemistry of the N-aminopropyl pendant arm derivatives (L1c–4c) of the mixed donor macrocyclic ligands [12]aneNS2O, [12]aneNS3, [12]aneN2SO, and [15]aneNS2O2 (L1a–4a) towards CuII, ZnII, CdII, HgII, and PbII in aqueous solution has been investigated. The protonation and stability constants with the aforementioned metal ions were determined potentiometrically and compared, where possible, with those of the unfunctionalised macrocycles. The measured values show that HgII and CuII in water have the highest affinity for all ligands considered, with the N-aminopropyl pendant arm weakly coordinating the metal centres. Crystals suitable for X-ray diffraction analysis were grown for the perchlorate salt (H2L1c)(ClO4)2·dmf, and for the 1 : 1 complexes [Cd(L3a)(NO3)2] (1), [Cu(L4a)(dmf)](ClO4)2 (2), [Zn(L1c)(ClO4)]ClO4 (3), [Cd(L1c)(NO3)]NO3 (4), and [Hg(L2c)](ClO4)2 (5). Their structures show the macrocyclic ligands adopting a folded conformation, which for the 12-membered systems can be either [2424] or [3333] depending on the nature of the metal ion. L1c–4c were also functionalised at the primary amino pendant group with different fluorogenic subunits. In particular the N-dansylamidopropyl (Lnd, n = 1–4), and the N-(9-anthracenylmethyl)aminopropyl (Lne, n = 1, 2, 4, Scheme 1) pendant arm derivatives of L1a–4a were synthesised and their optical responses to the above mentioned metal ions were investigated in MeCN/H2O (4 : 1 v/v) solutions." @default.
