Charge-transfer complexes of some linear conjugated polyenes.
On adsorption of some electron-acceptor molecules on the solid films of all-trans-beta-carotene, beta-apo-8'-carotenal, astacene and methylbixin a new absorption band appears on the longer-wavelength side of the spectrum in addition to the original bands. The position of this new band is dependent on the electron affinity (EA) of the acceptor molecules, and the intensity of this band increases ...
متن کاملGenealogy of Conjugated Acyclic Polyenes.
Based on the total π-electron energies Eπs of Hückel Molecular Orbital (HMO) method for all the possible isomers of conjugated acyclic polyenes (C₂nH₂n+2) up to n = 7, the structure-stability relation of the possible isomers was analyzed. It was shown that the mean length of conjugation L can roughly predict the ordering of stability among isomers, while the Z-index, or Hosoya-index, can almost...
متن کاملChemistry-Relevant Isospectral Graphs. Acyclic Conjugated Polyenes*
Abstract: By using the topological index Z and Z-counting polynomial proposed by the present author isospectral (IS) pairs of acyclic conjugated polyenes (C2nH2n+2) were studied. Besides the hitherto known smallest pair of n = 6, four and twenty seven pairs of n = 7 and 8, respectively, were first reported. Inspection of these results revealed several new features of IS tree graphs, i.e., appea...
متن کاملSynthesis and Optical Properties of Terminally Substituted Conjugated Polyenes
Compound 1 reacts with compounds of the transition metals Fe, Ni, Rh, Mn, Cr, or M o to form dark brown to black solids, whose insolubility and relative nonvolatility make their characterization difficult. However, black “FePlo,” formed immediately upon reaction with FeCI, in T H F at room temperature exhibits-like 1 -an IR band at 8 15 cm I, which is evidence for an intact aromatic Ps ring as ...
