K. Kalaiyarasan et al., PHOTOLUMINESCENCE OF 2-HYDROXYBIPHENYL AND ITS METHYL DERIVATIVE, Indian journal of chemistry. Sect. A: Inorganic, physical, theoretical & analytical, 33(4), 1994, pp. 335-337
The effect of solvents on the absorption and fluorescence spectra of 2
-hydroxybiphenyl and 2-methoxybiphenyl has been investigated. In the g
round state hydrogen acceptor interaction of 2-hydroxybiphenyl is more
predominant whereas in the excited state its hydrogen donor interacti
on is more effective. Analysis of photoluminescence of 2-hydroxybiphen
yl reveals its dual emission. The dual luminescence in polar solvents
is explained by the formation of solute-solvent exciplex with the tran
s isomer of the compound.
