Benzoporphyrins and Acetylene-Substituted Porphyrins as Improved Photosensitizers in the Photodynamic Tumor Therapy with Porphyrin Platinum Conjugates

Solvatochromic Stokes shift and determination of excited state dipole moments of free base and zinc octaethylporphyrin

“…Plotting ( m a À m f ) vs. F(e, n) and ( m a À m f ) vs. F 1 (e, n) (by using Eqs. (10) and (11), respectively) should give linear graphs with slopes m and m 1 , respectively. Therefore, using l g value, one can calculate l e independently from Eq.…”

“…A plethora of porphyrin derivatives have been extensively studied due to their fascinating photophysical and electrochemical properties [1][2][3][4][5][6][7][8][9][10][11][12][13][14][15][16][17][18]. Intrinsically, porphyrins are biogenic molecules responsible for various biological processes such as photosynthesis and respiration [19][20][21][22][23][24][25][26][27][28][29].…”

“…Intrinsically, porphyrins are biogenic molecules responsible for various biological processes such as photosynthesis and respiration [19][20][21][22][23][24][25][26][27][28][29]. Porphyrins have wide applications in solar energy harvesting and artificial photosynthesis [7][8][9][12][13][14][15][16][30][31][32], industrial processes as catalysts [1][2][3][4]6,[33][34][35], photodynamic therapy [11,17,36], anticancer pharmaceutical drugs [10] and photodynamic destruction of viruses [5,37]. Therefore, knowledge on the solvent dependent photophysical properties of porphyrin molecules is extremely important for designing molecular devices of medical, bio-medical and environmental importance.…”

Hydrogen bond controlled formation of trans-dihydroxo porphyrinato platinum(IV) complexes: Synthesis, characterization and catalytic activity in olefin epoxidation

“…Considerable attention has been paid to the oxidation of hydrocarbons catalyzed by Fe-, Mn-, and Ru-porphyrins [1,15,[25][26][27][28][29]. Although platinum porphyrins have been studied as oxygen sensing probes [30][31][32], photosensitizers [33][34][35], potential antitumor agents [36], and molecular conductors [37,38], there aren't any studies on platinum porphyrins as oxidation catalysts.…”

Some novel organometallic MnIII complexes with porphine and 1,6-diaminohexane

“…There has been growing interest [13,14] in Mn III porphyrins because of their reactivity and accessibility of several oxidation states that can be used for redox cycles useful for biochemical applications. They hold a special place in modern chemistry functioning as reaction catalysts, oxygen transporters, chemical sensors [15,16], anticancer pharmaceutical drugs [17] or in molecular electronic devices [18]. Mn III porphyrins using 5,10,15,20tetra-phenylporphines have been studied extensively [19][20][21].…”
