Phthalonitriles and metal-free phthalocyanines substituted with propane-1,2,3-triol and (2′,3′,5′,6′-tetrafluoro-4′-propane-1,2-diol)benzyloxy groups were synthesized. Their complexes with phenylboronic acid were prepared and characterized. Photophysical and photochemical properties of these phthalocyanines were investigated in ethanol and dichloromethane. The fluorescence quenching behaviour of the synthesized phthalocyanines were investigated using 1,4-benzoquinone in dichloromethane.
