Photoreduction of Self-Assembled Lipidporphyrinato-iron(III) Chloride with Hyaluronic Acid under Semi-Physiological Conditions

Photoirradiation into the LMCT band (λmax: 362 nm) of self-assembled amphiphilic tetraphenylporphyrinato-iron(III) (lipidporphyrinato-iron(III)) chloride with hyaluronic acid leads to reduction of the central ferric ion in saline solution (pH 7.4, 25 °C); the obtained lipidporphyrinato-iron(II) can reversibly bind and release dioxygen.
