Received: 11 March 2011; in revised form: 13 April 2011 / Accepted: 18 April 2011 / Published: 26 April 2011 Abstract: Eight novel compounds were prepared by reaction of 5-(bromo- propoxyphenyl)-10,15,20-triphenylporphyrin with oxazole thiols, 1,3,4-oxadiazole thiols and 1,3,4-thiadiazole thiols, and their structures confirmed by UV-vis, IR, 1H-NMR, MS and elemental analysis. The assessment of indirectly measured 1O production rates against 2 5,10,15,20-tetraphenyl porphyrin (H2TPP) were described and the relative singlet oxygen production yields were ：porphyrin 5 porphyrins 1, 3, 4, 6-8,
