Effects of 1-butanol on emission spectrum of 4-phenyl-1-N,N-dimethylaminobutane in THF: Separation into polar and hydrogen-bonding interactions
The effects of the addition of 1-butanol (BuOH), trichloroacetic acid (TCAA) and acetonitrile (AN) on the emission spectrum of 4-phenyl-1-N,N-dimethylaminobutane in THF have been studied. The results show that AN has only a polar effect and TCAA only a hydrogen-bonding (or protonation) effect, while BuOH has both effects. The relative magnitude of each effect was evaluated as a function of vol% of BuOH.
