Layered Hydroxide-Porphyrin Hybrid Materials: Synthesis, Structure, and Properties

Layered hydroxideporphyrin hybrids are attracting attention on account of their possible photophysical, photochemical, catalytic, and sensing applications. In comparison to free porphyrin and phthalocyanine molecules, the hybrids possess several potential advantages such as improved thermal and chemical stability, reduction of aggregation, tuning by layered hydroxide composition, and arrangement in transparent films. This review illustrates recent advances in the design, synthesis, and understanding of the structural alignment of bulky porphyrin-like molecules in the interlayer space. Special emphasis is placed on the utilization of their spectral and photophysical properties for the possible fabrication of light-triggered materials for bactericidal purposes. We describe examples from our laboratory and others, review their catalytic and sensing properties, and highlight the potential directions for further developments.
