We have reported drastic enhancement of photoluminescence of chiral Eu(III) complex (Eu(D-facam)3) in 1-butanol by cooperating effect of tetramethylammonium cation with specific counter anions of chloride and acetate. In this study, based on such unusual luminescence improvement, solvent effect of this luminescence enhancement was further investigated by comparing a series of primary alcs. with straight alkyl chains (carbon number, n : 1~6) including methanol, ethanol, 1-propanol, 1-butanol, 1-pentanol and 1-hexanol. In the case of both anions, notable alc. solvent effect on luminescence properties of Eu(D-facam)3 were observed upon coexistence with tetramethylammonium citation. Interestingly, in 1-pentanol, Eu(D-facam)3 achieved a superior luminescence enhancement above 500 times and induced circular polarized luminescence (glum = -0.69) by the interaction with tetramethylammonium acetate. On the contrary, the luminescence of Eu(D-facam)3 decreased by addition of tetramethylammonium acetate the in the methanol. The unusual optical behavior would be attributed to structural change of Eu(D-facam)3 induced by the interaction of tetramethylammonium and specific anions in alc. solution The strength of their interactions would be affected by polarity of the alc. solvents, leading to huge dependence of the luminescence intensity on the alc. species. This study involved multiple reactions and reactants, such as Tetramethylammonium chloride (cas: 75-57-0Related Products of 75-57-0).
Tetramethylammonium chloride (cas: 75-57-0) belongs to organic chlorides. An organic chloride is an organic compound containing at least one covalently bonded atom of chlorine. Their wide structural variety and divergent chemical properties lead to a broad range of names and applications. Alkanes and aryl alkanes may be chlorinated under free radical conditions, with UV light. However, the extent of chlorination is difficult to control.Related Products of 75-57-0
