Abstract:
1. A compound comprising the following porphyrin structure: or any pharmaceutically acceptable salt thereof, wherein: R R R or independently R M is either two hydrogen atoms or a metal ion; each n is independently an integer ranging from 1 to 20; each G is independently —H, or a C TPA is independently selected from the group consisting of the following structures TPA A through TPA H: wherein in TPA A, R is independently selected from the group consisting of H, alkyl, alkyloxy, and —(OCH G is H or alkyl, and m and n independently=1 to 5; wherein in TPA B, R is alkyl, and n=1 to 5; wherein in TPA C, R is independently selected from the group consisting of H, CN, alkyl, and alkyloxy, R′ is independently selected from the group consisting of alkyl, alkyloxyphenyl, phenyl, and phenyl-(OCH G is H or alkyl, and m and n independently=1 to 3; wherein in TPA D, R′ is independently selected from the group consisting of alkyl, alkyloxyphenyl, and phenyl-(OGH G is H or alkyl, and m and n independently=1 to 5; wherein in TPA E, R is independently selected from the group consisting of H, alkyl, and —OCH R′ is alkyl, G is H or alkyl, and m and n independently=1 to 5; wherein in TPA F, R is independently selected from the group consisting of H, alkyl, and —(OCH R′ is alkyl, G is H or alkyl, and m and n independently=1 to 3; wherein in TPA G, R is independently selected from the group consisting of H, CN, alkyl, alkyloxy, and —(OCH R′ is independently selected from the group consisting of H, alkyl, alkyloxy, and —(OCH G is H or alkyl, and m=1 to 6; and wherein in TPA H, R is independently selected from the group consisting of alkyl, phenyl, alkyloxyphenyl, and phenyl-[(OCH G is H or alkyl, m=1 to 4; and x=1 to 4; wherein in TPA A through TPA H, alkyl is C 1 to C 20 and the selected TPA is attached to the porphyrin structure at the point indicated by the wiggle line; Ar is independently C L is a linking moiety between the porphyrin structure and the TPA and is independently selected from the group consisting of ethenyl, ethynyl, —(CH wherein at least one of R 1 , R 2 or R 3 is a -TPA or -L-TPA moiety, and at least one of R 1 , R 2 or R 3 is not —H or a -TPA or -L-TPA moiety.
