Aromatic donor-acceptor interactions in non-polar environments.
We have evaluated the strength of aromatic donor-acceptor interactions between dialkyl naphthalenediimide and dialkoxynaphthalene in non-polar environments. (1)H NMR, UV-vis spectroscopy and isothermal titration calorimetry were used to characterise this interaction. We concluded that the strength of donor-acceptor interactions in heptane is sufficient to drive supramolecular assemblies in this...
متن کاملSecond sphere donor acceptor interactions in excited states of coordination compounds. Ruthenium(l1) bipyridine cyano complexes
Donor-acceptor interactions at the periphery of a coordination compound can have important consequences on its photochemical and photophysical behavior. Effects of this type have been explored using Ru(I1) bipyridine complexes containing cyanide ligands. The cyanide ligands of these compkxes behave a6 eLectroR donors in interactions with acceptor solvents, protonation, methylation, and bridging...
متن کاملAromatic donor-acceptor charge-transfer and metal-ion-complexation-assisted folding of a synthetic polymer.
Synthetic polymers typically adopt a random-coil conformation in solution primarily driven by the tendency to maximize entropy. Generation of well-defined secondary structures in synthetic polymers, therefore, will need to include specific intrachain intersegment interactions that will provide adequate enthalpic contribution to overcome this entropic penalty associated with the formation of wel...
متن کاملSignificance of CH/ Interactions on the Stability of Therapeutic Proteins
A computational analysis on the CH/ interactions in a group of 49 therapeutic proteins was investigated. A total of 77 CH/ interactions were observed. The donor atom contribution to CH/ interactions was mainly from aromatic residues. Long-range CH/ interactions are the predominant type of interactions in therapeutic proteins data set. The secondary structure preference, solvent accessibility an...
متن کاملCovalently linked acceptor-donor systems based on isoquinoline N-oxide acceptor: photoinduced electron transfer produces dual-channel luminescent systems that evolve chemically to photohydroxylation of the aromatic donor.
Acceptor-donor compounds containing the isoquinoline N-oxide acceptor and (methoxy)(n)benzene (n = 0, 1, 2, 3) electron donors were studied. The two chromophores are connected by a CH(2) bridging unit. All acceptor-donor compounds exhibit photoinduced electron transfer in acid medium that results in the formation of a charge-transfer (CT) state. Measurements of the corresponding electronic emis...
