The excited state dipole moment of 2-[(4-methoxyphenyl)ethynyl]-3-(1-methyl-1H-indol-3-yl)-quinoxaline from thermochromic shifts

The synthesis of several compounds related to ADMA are described in detail. These compounds are characterized by their mass, NMR, and IR-spectra. In addition, the solvent dependent shift of the fluorescence as well as the effect of an electric field on the fluorescence have been measured. The results are in agreement with a two-state model assuming the simultaneous fluorescence from a weakly polar and a highly polar state with dipole moment μ. μ2/a3 (a is Onsager’s radius) has been determined from both effects. The results are in good agreement with an excited state dipole moment of about 60 • 10-30Cm, in the polar state.

Polarity Of Solvents

In present work we explore the role of solvents on the 2, 5-dihydroxybenzoic acid by using fluorescence techniques. It was found that DHBA shows spectral behaviour depending on polarity of solvents. DHBA shows generally three components at 405-415nm, 430-450nm, and 450-470nm. The effects of zwitterion as well as the interplay ionic species are involved to explain the observed results
