✦ Synopsis
Steady-state fluorescence was used to measure the ratio of emission intensities, denoted I D /I M , for excited state complexes and excited monomers of five trichromophoric compounds, 2-naphthyl-COO-(CH 2 ) m -OOC-2,6-dinaphthyl-COO-(CH 2 ) m -OOC-2-naphthyl, m ϭ 2-6. The linear aliphatic alcohols H(CH 2 ) n OH, n ϭ 1-7, as well as mixtures of ethylene glycol and methanol, were used to change the viscosity of the medium, . The values of I D /I M depend on and m. A Rotational Isomeric State model and Molecular Dynamics simulations were used for interpretation of the experimental results.
