Thin films of weak charge-transfer complexes (pyrene/dimethylpyromellidiimide or pyrene/pyromellitic dianhydride) were investigated by time-resolve ESR, photoconductivity, and magneto-photoconductance measurements.

Wide Line

"Wide line" nuclear magnetic resonance studies of several charge transfer complexes are reported. Line width transitions and comparisons of theoretical and experimental second moments indicate that molecular rotation occurs in several of these complexes. Estimates of the barriers to reorientation in the complexes show these to be lower than those observed for the corresponding pure compounds.

Application of PMO treatment to 1,3-dipolar cycloaddition of C-benzoyl-N-phenylnitrone with furan derivatives is described. Ionization potentials of 2-R-substituted furan derivatives (R = H, CH3, C2H5, CH2OH, CH2OCOCH3, C6H5, CHO) and 2,5-dimethylfurane representing experimental values of the HOMO energies have been determined from energies of the respective charge-transfer complexes with TCNE. Good correlation between IP and k2 rate constants indicates that the reaction is controlled by the LUMO(nitrone)/HOMO(furan deriv.) interaction. Electron affinities of the furan derivatives were determined from IP and energies of π-π* transitions using empirical equation ΔE(π-π*) = IP-EA-450.58 kJ mol-1.
