Abstract
Manganese(II) complexes of [18]py 2N 4: 3,6,14,17,23,24-hexaazatricyclo[17.3.1.1 8,12]tetracosa-1(23),2,6,8(24),9,11,13,17,19,21-decane; [20]py 2N 4: 3,7,15,19,25,26-hexaazatricyclo[19.3.1.1 9,13]hexacosa-1(25),2,7,9(26),10,12,14,19,21,23-decaene; Bzo 2[18]py 2N 4: 3,10,18,25,31,32-hexaazapentacyclo[25.3.1.1. 12,16.0 4,9.0 19,24]dotriaconta 1(31),2,4(9),5,7,10,12(32),13,15,17,19,21,23,25,29-hexadecane and Bzo 2[18]py 2N 4: 2,10,16,24,30,32-hexaazapentacyclo[23.3.1.1 4,8.1 1,1,151 18,22otriaconta-1(29),2,4,6,8(32),9,11,13,15(31),16,18(30),19,21,23,25,27-hexadecane have been encapsulated in the nanopores of zeolite-Y by the template condensation reaction. Mn(II) complexes with macrocyclic ligand were entrapped in the nanocavity of zeolite-Y by a two-step process in the liquid phase: (i) the adsorption of [bis(diamine)manganese(II)]; [Mn(diamine) 2] 2+@NaY; in the supercages of the zeolite, and (ii) in situ condensation of the manganese(II) precursor complex with 2,6-diacetylpyridine. The new complex nanoparticles entrapped in the nanoreactor of zeolite-Y have been characterized by FT-IR, diffuse reflectance (DRS), X-ray photoelectron (XPS), thermal analysis, UV–Vis spectroscopic techniques, X-ray diffraction (XRD) and elemental analysis as well as by nitrogen adsorption.
