Although Phosphorus is perhaps one of the most well-known elements, a full understanding of its various allotropes and polymorphic subdivisions remains elusive. In concluding a general chemistry course, one may identify Phosphorus by three basic allotropes denoted by color: Red, White, and Black. However, owing to recent breakthroughs in nanomaterials, the allotropy of Phosphorus has broadened remarkably. Of these newly discovered forms, 1D nanorod structures, thought to be a derivative of Red Phosphorus polymorphs, are categorized by their resulting adduct character with metal halides. With a pure P nanorod surrounded by a metal interlayer and further encased by a halide layer, phosphorus metal halides (PMHs) have long been sought for their potential in identifying novel P nanorods that are stabilized within the structure. Furthermore, owing to their unique structure that combines the properties of a metal and a 1D phosphorus nanorod, they have recently seen an interest in electronic devices. To date, literature provides synthetic approaches that remain limited to CuI and CuBr with post-synthetic methods affording Ag2P3I2, though with significant drawbacks. In this work, we establish synthetic routes to expand this family to include a novel Br-containing structure and establish Raman spectroscopy as a valid characterization method. Further, we have extended the family to incorporate the metals Ag and Pb in the form of Ag3P10I2 and Pb3P15I2. The synthetic approach that affords such structures is believed to be applicable to various transition metals via the in situ formation of MPx, opening the door to extend the family of materials even further by introducing the MPx as a precursor. Novel applications of devices constructed with Cu2P3I2, Ag2P3I2, Cu2P3Br2, and Pb3P15I2 have been established as molecular sensors and FETs. The optimization of synthetic conditions, particularly as it relates to Ag3P10I2 has also revealed formation of large-scale Type II nanorods, a highly elusive polymorph of Red Phosphorus. Lastly, this work has encompassed another family of unique materials in the form of metal organic frameworks (MOFs). Herein, a particular variety of these porous materials, γ-CD-MOF-1, has been shown capable of sequestration of benzalkonium chloride (BAC), a common disinfectant. By utilizing chemical vapor diffusion to grow the MOF on polypropylene fabric prior to BAC loading, we have developed a novel surfactant-impregnated MOF-coated fabric for antimicrobial applications. These surfactant-impregnated MOF-coated pieces of fabric were successful in displaying strong antibacterial character against Pseudomonas aeruginosa, Staphylococcus aureus, and Escherichia coli, as well as strong antiviral character against T4 bacteriophage and a murine betacoronavirus. All antibacterial and antiviral character was established and validated with comparison against controls.
