protonate

The fluorescent tuning on and off can be achieved by the stimuli of acid, which will protonate the central nitrogen atom of triphenylamine unit to stop the PIET process.

通过加入酸将三苯胺中心氮原子进行质子化，切断其PIET过程，可实现荧光的淬灭与恢复的可逆性荧光调控。

However, they protonate and partly transfer to the outer surface of micelles in the acid titration process, and exist in very polar, solvent-accessible region of the inner.

而在酸性滴定中，经历了质子化，但未完全移至胶束界面外，而是存在于胶束内相对极性较强且溶剂可到达的区域。
