摘要：

The stabilization energies of the intramolecular dimer radical cations of carbazolyl, pyrenyl and naphthyl chromophores were determined from their charge-resonance absorption bands. The limited conformations of chromophores of 1,3-diarylpropanes and 2,4-diarylpentanes in their dimer radical cationic state facilities discussion of the stabilization energy at a fixed conformation. A sandwich-like full overlap conformation of both chromophores normally affords the largest attractive force. However, the repulsive force of ring overlap at a given conformation was found to be important in determining the total stabilization energy.
