We have explored the utility, strength, and limitation of through- space exciton-coupled circular dichro- ism in determination of the secondary structure of optically active chromo- phoric nanoarrays using the example of end-capped porphyrin– and metallo- porphyrin–oligodeoxynucleotide conju- gates. We put special emphasis on the explanation of the origin and signifi- cance of the distinctive multiple bands in the CD spectra (trisignate and tetra- signate CD bands). Such CD profiles are often observed in chiral aggregates or multichromophoric arrays but have never before been studied in detail.

Abstract
We have explored the utility, strength, and limitation of through- space exciton-coupled circular dichro- ism in determination of the secondary structure of optically active chromo- phoric nanoarrays using the example of end-capped porphyrin– and metallo- porphyrin–oligodeoxynucleotide conju- gates. We put special emphasis on the explanation of the origin and signifi- cance of the distinctive multiple bands in the CD spectra (trisignate and tetra- signate CD bands). Such CD profiles are often observed in chiral aggregates or multichromophoric arrays but have never before been studied in detail.File in questo prodotto:
