Meso-tetrakis(ferrocenylethynylphenyl) porphyrins: Synthesis and properties
چکیده انگلیسی


• New meso-tetrakis(ferrocenylethynylphenyl) porphyrins and zinc derivative are synthesized.
• The photophysical, electrochemical and computational studies have been performed.
• The para-linkage of the ferrocenyl unit in porphyrin P1 results in low HOMO–LUMO gap compared to meta-linkage in porphyrin P2.

We report the synthesis of meso-tetrakis(ferrocenylethynylphenyl) porphyrins P1, P2 and the zinc derivative ZnP2. The photophysical and electrochemical properties of these porphyrins show substantial donor–acceptor interaction. The computational studies reveal that the para-linkage of the ferrocenyl unit in porphyrin P1 provides better π-conjugation compared to meta-linkage in porphyrin P2, which results in low HOMO–LUMO gap and red shifted absorption. The porphyrin P2 and ZnP2 show better thermal stability compared to the porphyrin P1.
