sulfonic acid derivatives has been undertaken in solution at room temperature. The study includes absorption and emission spectra together with quantitative measurements of the deactivation of the first excited singlet state, from which the rate constants for all the decay processes has been obtained. A comparison on the gradual change of the electronic spectral and photophysical properties with the degree
氮的光谱,光物理和电化学研究-烷基ac啶酮,它们新合成的氯磺酰基和水溶性磺酸衍生物已在室温下在溶液中进行。该研究包括吸收光谱和发射光谱,以及对第一个激发单重态的失活的定量测量,由此获得了所有衰减过程的速率常数。考虑了电子光谱和光物理性质的逐渐变化与取代度的比较。另外,通过循环和微分脉冲伏安法获得了在不同pH值下的水溶性a烯的电化学行为。发现二磺化a啶酮的氧化机理发生在一个连续且不可逆的电荷转移pH依赖性反应中。发现水溶性a啶酮显示出长寿命值,这取决于pH值和溶剂极性。这为用作不同细胞环境和靶标的选择性探针打开了一扇门。
