摘要：

6, 6′-biquinoline (BQ) in aqueous-alcoholic solutions exhibits doubleluminescence and two ESR signals in the triplet state. The structureless fluorescence band observed at room temperature was shown to be the result of the protonation of strongly basic1 (BQ)* (pK* = 13). At low temperature the aggregation of the molecule has been observed. The low temperature absorption, luminescence, luminescence excitation spectra, and triplet ESR spectra of the aggregates have been measured and distinguished from the corresponding spectra of monomeric BQ. © 1979.
