A chiral porphyrazine (pz), H(2)[pz(trans-A(2)B(2))] (247), has been prepared that exhibits preferential in vivo accumulation in the cells of tumors. Pz 247 exhibits near-infrared (NIR) emission with lambda > 700 nm in the required wavelength range for maximum tissue penetration. When MDA-MB-231 breast tumor cells are treated with 247, the agent shows strong intracellular fluorescence with an e...
The electronic and vibrational Raman spectra of octa-substituted (R = –SC10H21) Coand Cu-porphyrazines are reported in their solid-state, mesophase, and isotropic liquid forms, as well as in THF solution. Their electronic spectra are composed of traditional Soret (CuS10 = 355 nm, CoS10 = 347 nm) and lower energy Q-bands (CuS10 = 669 nm, CoS10 = 639 nm), as well as a weaker, functionalityspecifi...
Phthalocyanines, naphthalocyanins, and their derivatives are frequently used as light modulating materials. These compounds, with their stable planar square structure and highly delocalized π-electron system, are being used in numerous technological applications, such as pigments in chemical sensors, and more recently as photosensitizers for photodynamic therapy. The nonlinear optical propertie...
A perfluorous polyphenyl dendritic shell for the protection of a photosensitizing porphyrazine core.
The implementation of thirty-two pentafluorophenyl groups in the periphery of a phthalocyanine analogue results in a photosensitizer with a pronounced resistance towards autophotooxidation. The synthesis relies on the microwave-assisted cycloaddition of terminal alkynes to tetrakis(pentafluorophenyl)cyclopentadienone, for which a new route was devised.
