Chemistry is the experimental and theoretical study of materials on their properties at both the macroscopic and microscopic levels.In a patent， name: 1,4,8,11-Tetramethyl-1,4,8,11-tetraazacyclotetradecane, Which mentioned a new discovery about 41203-22-9
Organic?inorganic iodoplumbate hybrids [Ni(en)2]2Pb3I10 (1), [Ni(en)3]Pb2I6 (2) (en = ethylenediamine), [Ni(dien)2]Pb2I6·H2O (3) (dien = diethylenetriamine), [Ni(14-TMC)][PbI3]2·DMF (4), and [Ni(14-TMC)]2[Pb5I14(DMSO)2] (5) (14-TMC = 1,4,8,11-tetramethyl-1,4,8,11-tetraazacyclotetradecane) were prepared using different NiII complex cation as structural directing agents under solvothermal conditions. Compounds 1?4 consist of 1-D [Pb3I104?]n, [PbI3?]n and [Pb2I62?]n polymeric anions constructed by PbI6 octahedra via corner-, edge- or face-sharing, respectively. The novel organic hybrid iodoplumbate anion [Pb5I14(DMSO)24?]n in 5 is composed of PbI6 and PbI5O octahedra via edge- and face-sharing. The formation of polymeric iodoplumbate anions in 1?5 indicates different structure-directing effect of the NiII complex cations with various polyamino ligands under appropriate reaction and crystallization conditions. Compounds 1?5 exhibit tunable band gaps varying in the range of 2.18?2.61 eV. Compounds 4 and 5 are more effective than 1 and 3 in the photocatalytic degradation of methylene blue.
Because enzymes can increase reaction rates by enormous factors and tend to be very specific, name: 1,4,8,11-Tetramethyl-1,4,8,11-tetraazacyclotetradecane, typically producing only a single product in quantitative yield, they are the focus of active research.you can also check out more blogs about 41203-22-9
