The application of merocyanine photoacids has previously been largely limited to neutral and acidic pH values. Here we introduce a new merocyanine photoacid with superior pH switching qualities. By increasing the p in the dark (pdarka) and the solubility we increased the reversible visible light induced pH jump to 3.5 units. Moreover, it is the first demonstration of a merocyanine photoacid able to generate a significant pH drop from a basic (pH 8.3) to an acidic (pH 5.2) environment.
部花青光酸的应用此前在很大程度上局限于中性和酸性pH值范围。在此，我们介绍一种具有卓越pH转换特性的新型部花青光酸。通过提高其在黑暗中的p值（p暗）和溶解度，我们将可逆可见光诱导的pH跃升至3.5个单位。此外，这是首次证明一种部花青光酸能够在从碱性（pH 8.3）到酸性（pH 5.2）的环境中产生显著的pH下降。
