Corroles of formula I, wherein Ar is aryl or heteroaryl; M is absent or is a metal selected from Al, Ga, Co, Mn, Fe, Ru, Sn, Cr or Rh; E<SUB>2</SUB>, E<SUB>3 </SUB>and E<SUB>17</SUB>, the same or different, each is H, SO<SUB>2</SUB>Cl, SO<SUB>3</SUB>H, SO<SUB>2</SUB>NR<SUB>1</SUB>R<SUB>2</SUB>, CO<SUB>2</SUB>H, CO<SUB>2</SUB>R, COC<SUB>1</SUB>, CONR<SUB>1</SUB>R<SUB>2</SUB>, CHO or NO<SUB>2</SUB>, R is alkyl or aryl, and R<SUB>1 </SUB>and R<SUB>2</SUB>, the same or different, each is H, alkyl, aryl or together with the N atom to which they are attached form a saturated 5-6 membered ring optionally containing a further heteroatom selected from O, S and N; and E<SUB>18 </SUB>is H or CHO; or E<SUB>3 </SUB>and E<SUB>18 </SUB>are H and E<SUB>2 </SUB>and E<SUB>17 </SUB>are each SO<SUB>2</SUB>, both SO<SUB>2 </SUB>groups being linked by a bridge R<SUB>3</SUB>N(R<SUB>4</SUB>)-phenyl-(R<SUB>4</SUB>)NR<SUB>3</SUB>, wherein R<SUB>3 </SUB>is H, alkyl, phenyl or aralkyl, and R<SUB>4 </SUB>is alkylene; and provided that at least one of E<SUB>2</SUB>, E<SUB>3</SUB>, E<SUB>17 </SUB>and E<SUB>18 </SUB>is not H, are provided. The corroles can be used for tumor detection and treatment, in photovoltaic devices, as catalysts and as intermediates. |
