Polyalkoxy substituted phthalocyanines sensitive to phenolic compounds in water

- New phthalocyanines are introduced for chemical sensing in water.
- Clear trend in sensitivity and selectivity with modifications made to the Pcs.
- Selectivity is governed by substituent, sensitivity mainly by metal ion center.
- High sensitivity to phenolic compounds with detection limits down to 0.01 mg/ml.
- Highest reported sensitivity of a Pc in liquid sensing applications with the QCM.
