A new family of metal organic frameworks, namely Alkali‐Phosphonate‐MOFs, has been reported. The new alkali‐phosphonate‐MOF shows exceptional thermal stability and has a high surface area due to rectangular void channels.

In this study, a novel asymmetrically meso-substituted AB3 porphyrins derivative including one triazole group to enhance the anticancer activity of the molecule and three bromophenyl groups to improve photochemical properties has been synthesized and characterized. Our objectives were to generate a system with triazole and bromophenyl groups that enhance the singlet oxygen generation and exhibits an anti-cancer effect. Therefore, photophysical and photochemical properties of this asymmetric porphyrin derivative (AB[Formula: see text] and the symmetric derivative (B[Formula: see text] were investigated in THF. The substituent effect on fluorescence quantum yield and singlet oxygen generation was evaluated for efficiency in photodynamic therapy (PDT) as a photosensitizer. The molecules exhibited no aggregation tendency, solubility in common organic solvents and high singlet oxygen quantum yield in THF therefore these favorable properties make them good candidates as a photosensitizer for PDT.
