Five Covalent Organic Frameworks (COFs) were synthesized and applied to Dye-Sensitized Solar Cells (DSSCs) as dyes additives. These porous nanomaterials are based on cheap, abundant commercially available ionic (thionin acetate RIO-43, Bismarck brown Y RIO-55 pararosaniline hydrochloride RIO-70), antibiotics (dapsone RIO-60) used building blocks. The reticular innovative organic framework RIO-60 is the most promising dye for DSSCs. It possesses a short-circuit current density (Jsc) of 1.00...
This study reports a novel family of cage manganesesilsesquioxanes prepared via complexation with bathophenanthroline (4,7-diphenyl-1,10-phenanthroline). The resulting Mn4-, Mn6Li2-, and Mn4Na-compounds exhibit several unprecedented metallasilsesquioxane structural features, including intriguing self-assembly silsesquioxane ligands. Complexes were tested in vitro for fungicidal activity against seven classes phytopathogenic fungi. representative Mn4Na-complex acts as catalyst the...
Locust bean gum (LBG) is a natural polymer that belongs to the increasingly attractive biodegradable mesoporous matrices prepared from ionic liquids and scCO<sub>2</sub>sustainable method.
Three new zinc(II) complexes [Zn(H2L3)2(H2O)3] (Zn2), [Zn(H3L2a)(H2O)3]n (Zn3) (H3L2a = 2,4-diiodo-5-(2-(2,4,6-trioxotetrahydropyrimidin-5(2H)-ylidene)hydrazineyl)isophthalate) and [Zn(HL4)(DMF)(H2O)]n (Zn4) were synthesized by the reaction of Zn(II) salts with 5-(2-(2,4-dioxopentan-3-ylidene)hydrazineyl) isophthalic acid (H3L3), 2,4,6-triiodo-5-(2-(2,4,6-trioxotetrahydropyrimidin-5(2H)-ylidene)hydrazineyl) (H5L2) (in presence NH2OH·HCl)...
