Di-, Tri-, and Tetranucleating Pyridyl Ligands Which Facilitate Multicenter Magnetic Exchange between Paramagnetic Molybdenum Centers

Molecular Structure–Function Relations of the Optical Properties and Dimensions of Gold Nanoparticle Assemblies

“…A series of CLs with one to four pyridyl moieties (1-6, Scheme 1) [5,6] were reacted with solutions of citrate-capped AuNPs with a homogeneous size distribution of (11.8 AE 1.3) nm ( Figure S1 in the Supporting Information). In particular, solutions of the CLs in THF were added stepwise to aqueous solutions of freshly prepared AuNPs.…”

Organic–inorganic hybrid matrix doped with alkenyldiazenido complexes of molybdenum

“…These bands occur in the same range of high-energy charge-transfer band at λ max = 250-300 nm for [MoL][BPh 4 ], which prevents a direct proof of the immobilization of the metal complex inside the hybrid matrix. The shoulder band at 510 nm associated to diazoalkene-p to the metal-d charge-transfer transitions [22] are not observed probably due to low concentration of metal complex in hybrid matrix even in the sample with higher concentration of molybdenum complex.…”

“…In the electronic spectroscopic data of molybdenum complex, the major feature displayed by these complexes [22] is multiple bands in the range 250-300 nm and a shoulder peak in 510 nm. These absorptions are assigned to the diphenylphosphine ligands (-* transition) and diazoalkene-p to the metal-d chargetransfer transitions, respectively.…”

Co-assembly of Zn(SPh)2 and organic linkers into helical and zig-zag polymer chains

“…Zn 2 þ and SPh À sources are either in the form of Zn(SPh) 2 (which was synthesized according to the reported procedure [12]) or in the form of Zn(OAc) 2 Á 2H 2 O and HSPh. Organic linker BPyVB was synthesized and purified according to reported procedures [13] while TPyTA was directly bought from TCI Singapore and was used without further purification. [Zn(SPh) 2 (TPyTA)(EG)] n .…”
