New Designs in Photovoltaic Materials: We are working on the

development of a new designs for future generations of photovoltaic materials, focusing on overcoming several of the considerable obstacles currently limiting existing devises. One of our approaches, involves a pathway that has not thus far been explored and utilizes a multi-component system incorporating an electron reservoir macrocyclic system that is coupled to both a photosensitizer, such as a dye molecule, and a semiconductor electron transport material. In this arrangement, an absorbed photon can cause a one-electron photoreduction of the reservoir via photon absorption, electronic excitation and injection from an

attached dye or donor molecule into the reservoir. Spatial and orbital barriers to recombination can be designed to provide a sufficient lifetime of this reservoir’s excited state for promotion of the electron into a high enough energy level through independent photochemical steps to be either irreversibly injected into the conduction band of the attached semiconductor, or by the removal of the hole by the electrolyte, typically through a diffusion-controlled process. Several types of electron reservoirs are being investigated, including carborane-based macrocycles and donor-bridge-acceptor systems (such as shown in Figure 1). Functionalized borane and carborane cages are well known to be exceedingly stable species that undergo multiple redox steps, and molecular orbital calculations suggest that these macrocycles will serve well in the electron-reservoir capacity These systems provide a significant degree of potential chemical tailoring of electronic properties that should make them particularly interesting as new and efficient photovoltaic cells.

A second approach uses the straightforward noncovalent functionalization and solubilization of hexagonal-boron nitride nanosheets (BNNSs) by reacting various polymers, such as polythiophene or polyvinylpyrrolidone polymers, with exfoliated BNNSs. BNNS are boron analogs of grapheme, but with some quite different chemical and electrical properties desirable for various applications. The boron nitride nanosheets apparently form strong π − π stacking interactions with the polymers to yield stable derivatized nanosheets with modified properties. These functionalized polymers, tethered to the exfoliated BNNSs, can be further coordinated to pre-formed TiO2 nanoparticles to form more complex BNNS-polythiophene-(CH2)n-COO-TiO2 hybrid nanomaterials through covalent binding, including electron delocalized systems. The resultant stable BNNS-polythiophene heterostructures form a platform for entirely new hybrid systems combining both boron nitride nanosheets and inorganic nanoparticles. These heterostructures have now been found to generate a photocurrent upon exposure to light.

New Ultra Sensitive and Selective Sensors:
In the second area of our work, we are developing exciting new generations of sensors with extreme response and selectivity properties. These sensors are based upon the use of modified and/or functionalized piezoelectric solid state systems, especially Quartz Crystal Monitor-based (QCM) devices. QCM-based devices, utilizing this approach, have been used for decades for measuring mass changes during deposition processes. Sensors based upon the electronic response (e.g., frequency, phase and/or jitter) of such piezoelectric devices to surface-bound mass provides an excellent platform for the selective detection of key target molecules. In our work, we are employing piezoelectric-based functionalized solid state materials to detect with ppb (or better) sensitivity and exceptional selectivity molecules of specific targeted interest. We are collaborating with a group from engineering to prepare devices with unique properties for a variety of technological problems, including rapid medical diagnostics, environmental monitoring and threat agent detection. Recent advances for our team regarding the measurement and processing of electronic information from these systems have the potential to significantly enhance the operation and increase the sensitivity of these devices.

Polyhedral Chemistry:
In a third area of our work, we are exploring the chemistry of main group polyhedral clusters. The field spans the boundaries of traditional areas of inorganic, organometallic, and materials chemistry. Specifically, our research has focused upon the study of polyhedral based as new nonlinear optical compounds, the photochemical reactions of clusters, and the use of cluster and rigid molecules as molecular building blocks in the directed formation of nanoscale architectures. Main group and organometallic clusters have presented considerable challenges to synthetic, structural, materials and theoretical chemists since their discovery nearly ninety years ago. The quest for a detailed understanding of the bonding and structural relationships of these species has led to an understanding of some of the fundamental chemistry of molecular polyhedra in general.

The study of polyhedra, many-faced solids, has long intrigued and fascinated scientists and philosophers. Plato first described a series of five "pure" polyhedral bodies from which Archimedes later elegantly derived 13 semi-regular polyhedra. The field of cluster chemistry, however, most closely ties together the abstract study of pure polyhedra with the physical and chemical world. In particular, cluster chemistry may be thought of as the practical bridge between small molecule behavior, with more localized bonding, and that of extended solid arrays, with extensively delocalized electronic structures.

A further aspect of our work focuses upon the development of new solid state boron-based materials as thin films, nanoparticles, and nanotubes. These materials display an enormous range of physical and chemical properties that have direct application to many areas. We have recently discovered several new chemical pathways for the formation of thin films of metal borides, along with the first-reported pathways for the fabrication of boron-based nanotubes and nanorod structures. These unique structures, for instance, are readily prepared, are remarkably uniform, and display very large aspect ratios.
