Nanoarchitectonics with Porphyrin Functionalized DNA

Nanoarchitectonics with Porphyrin Functionalized DNA

DNA is well-known as bearer of the genetic code. Since its structure elucidation nearly seven decades ago by Watson, Crick, Wilkins, and Franklin, much has been learned about its detailed structure, function, and genetic coding. The development of automated solid-phase synthesis, and with it the availability of synthetic DNA with any desired sequence in lengths of up to hundreds of bases in the...

DNA nanoarchitectonics: assembled DNA at interfaces.

DNA is a powerful biomaterial for creating rationally designed and functionally enhanced nanostructures. DNA nanoarchitectures positioned at substrate interfaces can offer unique advantages leading to improved surface properties relevant to biosensing, nanotechnology, materials science, and cell biology. This Perspective highlights the benefits and challenges of using assembled DNA as a nanosca...

Porphyrin - functionalized oligo - and polythiophenes {

The synthesis and properties of a series of biand terthiophenes 3–8 substituted with meso-tetraphenylporphyrin (TPP) groups via an isolating oxaalkyl chain is described. Electrooxidative polymerization leads to the corresponding metal complexed porphyrin-functionalized polythiophenes P4–P8. The electrochemical and spectroscopic properties of the polymer films reveal the superimposition of the e...
