Course Outline: Fundamental Chemistry of Nanomaterials: Bonding and Periodicity

During this course students will study the bonding of nanomaterials form a chemical perspective. This will entail a cursory coverage of quantum mechanics, periodicity, and spectroscopic techniques related to characterization of nanomaterials. We will use the building block approach, i.e., first students will demonstrate and understanding of the concepts of bonding and spectroscopy for molecules, then these concepts will be applied to materials, nanaomaterials, and bulk materials. The discussion of specific classes of nanomaterials will be done by periodic groups: carbon, other s- and p-block materials, transition metals (both coordination and organometallic complexes), and the f-block, with special focus on lanthanide elements.

This course outline assumes a 15 week semester with class meetings twice per week for 1 hour and fifteen minutes (we include material for 27 lecture periods, leaving the remainder free for special lectures, exams, or other topics). The approximate time spent on each subject is given along with a brief description of possible topics. Course materials would include a brief text on quantum chemistry, one on descriptive aspects of materials and nanomaterials, and recent literature as appropriate to the material and institution. While there are several inorganic textbooks that contain all the material proposed, they also contain a substantial amount of additional material; therefore, we suggest the following two texts for the course:

Hayward, ^ Quantum Mechanics for Chemists,

Fahlman, Materials Chemistry, Springer, 2007.

Course outline:

  1. Periodic Trends and basic definitions- Bonding and Periodicity (2 lectures)

Basic review of periodic trends such as size, electronegativity, electron configurations, etc…

Definitions of materials, nanomaterials, discussion of applications, and discussion of macro vs. micro vs. nano.

  1. Bonding theories (2 lectures)

Review of Lewis theory, molecular geometry (i.e., ED, VSEPR), hybridization, MO theory for diatomics

  1. Quantum Mechanics (6 lectures)

    1. History from Blackbody radiation through the Schrödinger wave equation

    2. Particle in a well of infinite potential

    3. Harmonic and anharmonic oscillators

    4. Rigid rotor

    5. The hydrogen atom

  2. Molecular Orbital Theory (2 lectures)

Brief coverage of molecular orbital diagrams for higher-order molecules. We would not recommend a true group theoretical treatment but would expect at least a cursory explanation of the origin and importance of symmetry labels

  1. Photoelectron spectroscopy (2 lectures)

Description of the photoelectric effect and applications to molecular orbital theory and materials analysis

  1. Other spectroscopies (2 lecture)

Vibrational spectroscopies (i.e., IR and Raman) and magnetic spectroscopies (NMR, EPR, SQuID)

  1. Bonding in Materials (4 lectures)

Discussion of band theory, insulating, conducting, semiconducting and superconducting properties; lattice vibrations and heat capacity in materials and bulk samples. Application of XPS to materials analysis would be included.

  1. Carbon nanomaterials (2 lectures)

History, synthesis, spectroscopy, and materials properties of fullerens, nanotubes, and graphines. Current advances will be discussed.

  1. Main group nanomoaterials (2 lectures)

History, synthesis, spectroscopy, and materials properties of p-block nanomaterials (both pure and doped). Current advances will be discussed.

  1. Transition metal nanomaterials (2 lectures)

History, synthesis, spectroscopy, and materials properties of coordination and organometallic nanomaterials. Current advances will be discussed.

  1. f-block nanomaterials (1 lecture)

Topics 1-7 are well established pedagogical areas; therefore, there are myriad text resources available to instructors to prepare varied examples for lectures. Topics 8-11, while available in some texts, necessarily require familiarity with the current literature. While not every institution has access to field specific journals (such as Nanoletters), instructors can find enough material on these topics in more general journals such as J. Am. Chem. Soc., Inorg. Chem., Phys. Rev., etc…
