Doping control via molecularly engineered surface ligand coordination.
نویسندگان
چکیده
A means to control the net doping of a CQD solid is identified via the design of the bidentate ligand crosslinking the material. The strategy does not rely on implementing different atmospheres at different steps in device processing, but instead is a robust strategy implemented in a single processing ambient. We achieve an order of magnitude difference in doping that allows us to build a graded photovoltaic device and maintain high current and voltage at maximum power-point conditions.

In the title compound, [Hg(C(12)H(11)N(4)S(2))I(C(12)H(12)N(4)S(2))], the Hg atom is in a distorted square-pyramidal coordination, defined by the iodide ligand, by the S atom of the neutral ligand in the apical position, and by the N atom of the thia-zole ring, the thio-ureido N and the S atom of the deprotonated ligand. The deprotonated ligand intra-molecularly hydrogen bonds to the thia-zole ...

A modified electrochemical sensor for the determination of amoxicillin (AMX) was reported in this paper. The magnetic molecularly imprinted polymer (MMIP) were suspended in AMX solution and then collected on the surface of a magnetic carbon paste electrode (CPE) via a permanent magnet, situated within the carbon paste electrode and then the voltammetry signals were recorded. It was confirmed th...
متن کاملSynthesis and characterization of mono- and heterodinuclear complexes of dinucleating macrocyclic ligand bearing hexa- and pentadentate coordination sites
Macrocyclic heterobinuclear Zn(II)–Cu(II) complexes with phenol based dicompartmental ligands possessing contiguous hexa- and penta-coordination sites were prepared by a stepwise procedure. The ligands include similar N4O2 and dissimilar N(imine)3O2 and N(amine)3O2 coordination sites sharing two phenolic oxygen atoms. The six-coordination site comprises two pyridyl pendant arms on the amine nit...
متن کاملSubstrates for cell adhesion prepared via active site-directed immobilization of a protein domain.
Recent studies in basic cell biology and bioengineering call for model substrates that present active proteins, with control over protein density, pattern, and orientation, to more directly mimic the natural extracellular matrix. Herein we demonstrate a strategy for controlled, irreversible immobilization of a cell adhesion protein domain onto an otherwise bioinert substrate with well-defined p...
