Synthesis and characterization of dendritic poly(l-lysine) containing porphyrin–fullerene moieties

[80]Fullerene–amino acid interactions: Theoretical insights

“…We have also shown the fullerene–amino acid binding energies (labeled as Δ E C60 ) that are extracted from Ref. 15(c).…”

“…The present report is directed at examining the effect that a more reactive fullerene has on the binding strength with the 20 naturally occurring amino acids. In other experimental studies, advancements in synthetic techniques have lead to the fullerene–amino acid polymers to be constructed 15(a,b). To this end, we provided calculations that show that the fullerene species interacts most favorable with arginine, leucine, and tryptophan 15(c) with binding energies of −3.0, −3.9, and −2.4 kcal/mol, respectively.…”

Therefore, the stability of the binding energies leads us to suspect that the extension of this work to the C 80 case may resemble similar or improved trends.…”

Synthetic Aspects of Porphyrin Dendrimers

“…Prato et al also prepared a dendritic fullerene–porphyrin dyad, the structure of which includes a G 2 cyanobiphenyl‐based liquid‐crystalline dendron 56e. Water‐soluble amphiphilic poly( L ‐lysine) dendrons with carboxylate terminals and links to porphyrins (and a fullerene) were prepared by Nishino et al56f,56g Fréchet‐type dendrons attached to the axial position of a Rh III –porphyrin through their focal dialkoxybenzyl groups were synthesized as novel carbon‐centered free‐radical equivalents by Kimata and Aida 56h. Aida and associates also reported the synthesis and self‐assembly of an amphiphilic Zn–porphyrin–fullerene dyad with a G 1 benzyl ether dendron carrying triethyleneglycol end groups attached to one of the meso positions 56i.…”

Synthetic Strategies towards Fullerene-Rich Dendrimer Assemblies

“…Measuring the charge-separated state of the supramolecular complex produced upon laser excitation had a particular long lifetime of 0.25 ms. Similarly, Ogawa et al exploited the same fulleropyrrolidine 84 for the complexation with zinc porphyrins [56]. Upon the preparation of a π-conjugated porphyrin polymer, this molecular wire has been subjected to the coordination by 84.…”
