Abstract
Oxalate sensitivity and selectivity to H2O2 are suggested as criteria for choosing the substrates for chemiexcited PDT. An increase in oxalate electronegativity decreases both values. The presence of o-substituent increases efficiency of aromatic oxalate. Oxalate encapsulation in micelles does not change the patterns observed in solution. Biocompatible bis(2-pentyloxycarbonyl-phenyl)oxalate synthesized for the first time is promising oxalate for chemiexcited PDT.
