wherein R.sub.1 is selected from (C.sub.1-C.sub.8) alkyl groups and OR.sub.2 is selected from (C.sub.1-C.sub.8) alkoxyl groups.

A method of synthesis of metal organic frameworks (“MOFs”) includes preparing a metal solution by dissolving at least one metal salt in an aqueous solution and buffering the metal solution with a base to achieve a first pH, the metal solution optionally comprising an organic co-solvent, preparing a linker solution by adding at least one organic acid linker and at least one base to an aqueous solution, and mixing the metal solution and the linker solution to produce the MOFs. The at least one organic acid linker has an ability to be protonated or deprotonated in response to a second pH, and the mixture of the metal solution and the linker solution has a third pH value, where the third pH value is greater than a highest pK.sub.a of the organic acid linker. The MOFs may be applied to a textile.

Large scale (bulk) compositions comprising high-purity stannsoporfin are disclosed, as well as methods of synthesizing such compositions.
