Building blocks

The possibilities to design and develop new materials for applications such as dye-sensitized solar cells and solar fuels are virtually endless. Our experience has shown that it is highly valuable to have a set of reproducible starting materials, building-blocks, that are readily available so the efforts can be focused on novel materials. For the time being, Dyenamo provides ten such building blocks, offering you the possibility to rapidly and cost-efficiently assemble advanced molecules of your own design.

Ligands for metal complexation

DN-BB05

bpyPY4








Description:
bpyPY4 is a versatile ligand that can be used as a multidentate ligand to many different metal ions. As an example, cobalt complexes such as Co(bpyPY4)(PF6)2 and Co(bpyPY4)(PF6)3 can be produced, for improved stability of DSSC devices. Another example is the iron complexes Fe(bpyPY4)(OTf)2 and Fe(bpyPY4)(OTf)3, used as hole-transporting materials in Perovskite solar cells.

Full name:
6,6'-bis(1,1-di(pyridin-2-yl)ethyl)-2,2'-bipyridine

CAS number:
1443276-90-1

Typical properties:
MW = 443.54 g/mol

DN-BB06

tmby







Description:
tmby is a versatile ligand that can be used as a multidentate ligand to many different metal ions. As an example, it is used in the production of the copper based redox couple Cu(tmby)2TFSI1/2. Dyenamo also provides the ready-made copper complexes, under the product codes DN-Cu09 (Cu(tmby)2TFSI) and DN-Cu10 (Cu(tmby)2TFSI2).
