摘要：

A dual-emission pH-sensitive fluorescent probe was developed, which displays green fluorescence in alkaline after deprotonation, while orange emission in acid at aggregated state. This novel probe allows the specific light-on in acidic lysosomes of cancer cells and tumors in nude mice, which indicates its potential application in cancer diagnosis.
