The neutral europium complex [EuL
1
] shows a pH dependent
luminescence enhancement of over 500, while in the N-methylated
analogue the metal-based luminescence is selectively quenched by chloride
and (above pH 10) by hydroxide anions.
中性铕络合物[EuL 1 ]的发光强度随 pH 值的变化而增强,超过 500,而在 N-甲基化类似物中,金属基发光被氯离子和(pH 值高于 10)氢氧根阴离子选择性地淬灭。
