Sulfonyldibenzoate coordination polymers as bioactive dopants for polysaccharid...
Fernandes, Tiago A.; Macedo, Filipa; Cabral, Rafaela G.; Guiu, Telma; Franco, Chris H. J.; Jorge, Paula; Sousa, Ana Catarina; André, Vânia; Cerca, NunoThis work describes the preparation, characterization, and antimicrobial properties of bioactive silver(I) and copper(II) coordination polymers (bioCPs) and derived biopolymer materials. Two bioCPs, [Ag2(6-sdba)]n (1) and [Cu(4-sdba)H2O]n·1.5nH2O (2), were assembled from metal salt precursors and 4,4-sulfonyldibenzoic acid (H2sdba). Both compounds were used as dopants for preparing hybrid biopolymer films based...

Hybrid silver(I)-doped soybean oil and potato starch biopolymer films to combat...
Fernandes, Tiago A.; Costa, Inês F. M.; Jorge, Paula; Sousa, Ana Catarina; André, Vânia; Cabral, Rafaela G.; Cerca, Nuno; Kirillov, Alexander M.This study describes the preparation, characterization, and antimicrobial properties of novel hybrid biopolymer materials doped with bioactive silver(I) coordination polymers (bioCPs). Two new bioCPs, [Ag2(6-hfa)]n (1) and [Ag2(4-nda)(H2O)2]n (2), were assembled from Ag2O and homophthalic (H2hfa) or 2,6-naphthalenedicarboxylic (H2nda) acids as unexplored building blocks. Their structures feature 2D metalorganic...

Silver(I) coordination polymers immobilized into biopolymer films for antimicro...
Fernandes, Tiago A.; Costa, Inês F. M.; Jorge, Paula Alexandra Silva; Sousa, Ana Catarina; André, Vânia; Cerca, Nuno; Kirillov, Alexander M.This study describes a template-mediated self-assembly synthesis, full characterization, and structural features of two new silver-based bioactive coordination polymers (CPs) and their immobilization into acrylated epoxidized soybean oil (ESOA) biopolymer films for antimicrobial applications. The 3D silver(I) CPs [Ag4(?8-H2pma)2]n·4nH2O (1) and [Ag5(?6-H0.5tma)2(H2O)4]n·2nH2O (2) were generated from AgNO3 and p...

New silver (thio)semicarbazide derivatives: synthesis, structural features, and...
Fernandes, Tiago A.; André, Vânia; Arol, Aliaksandr; França, Ângela Maria Oliveira Sousa; Mikhalyonok, Sergei; Cerca, Nuno; Kirillov, Alexander M.Two novel semicarbazide [HL1, 1, 1-((4-nitrophenyl)(phenyl)methylene)semicarbazide] and thiosemicarbazide [HL2, 2, 1-((4-nitrophenyl)(phenyl)methylene)thiosemicarbazide] ligands were generated from 4-nitrobenzophenone and the corresponding (thio)semicarbazide precursors. Compounds 1 and 2 were fully characterized and their X-ray crystal structures were established. These organic derivatives were further applied...
