| Course description |
| Organic materials comprise organic molecules and the characteristics mostly depend on those of the constituents. Since the structures, reactions, and functionalities of the molecules are governed by the behaviors of the electrons, it is of fundamental importance to design organic materials with your eyes set on the electronic structures. Following the relevant undergraduate courses, this course discusses methodologies for examining the electronic structures and properties of organic molecules. |
| Expected Learning |
|
Learners who successfully complete this course will be able to (1) revive their skills in microscopic physical chemistry, likely to be deteriorated during graduation research; (2) examine the electronic structures, stability, and reactivity of molecules with paper and a pencil; (3) gain a foothold for further self-study to carry out quantum chemical calculations or read through the literature of this fields. Corresponding criteria in the Diploma Policy: See the Curriculum maps. |
| Course schedule |
|
Week 1 Examination to check the students' comprehension (or forgetting) of microscopic physical chemistry. Main scope of the examination: quantum chemistry I･II and structural chemistry. Week 2 Review of fundamental items, e.g., Meaning of wave function; AO energy and distribution; Hydrogenic atoms and many-electron atoms; Variation principle; LCAO approximation; Bonding and antibonding MOs; Hueckel approximation. Week 3 Rules of orbital interaction: One-to-one (review); Two-to-one (derivation); MO construction for a heteronuclear diatomic molecule without hydrogen. Week 4 Application of group theory to MO construction (review); Walsh diagram - relationship between geometric and electronic structures. Week 5 Application of quantum chemistry to polymers: Energies and wave functions of polymer MOs dependent on the conformation. Week 6 Construction of π electronic systems in carbonyl compounds, benzene, and heterocycles; Aromaticity; Interpretation of computer outputs of empirical calculations for fundamental molecules. Week 7 Reactions governed by interaction between the HOMO of chemical species A and the LUMO of chemical species B; Regioselectivity and the electron distribution of the HOMO and LUMO. Week 8 Reactions forming two bonds simultaneously between chemical species A and B: Stereoselectivity governed by orbital symmetry. Expedient separation of a molecule into two parts (an electron donor and an electron acceptor): In-phase HOMO-LUMO interaction yielding the main product. Week 9 Retention or inversion of stereochemistry in reactions; Orbital phase continuity conditions; Conservation of orbital symmetry; Orbital correlation diagram; Symmetry allowed and forbidden reactions. Week 10 Experimental methods to survey the electronic structures of organic molecules and aggregates: From the standpoint of energies and that of wave functions. Week 11 Variational calculation for Li using the product of three orbitals of the same type and the wrong result; Pauli principle and antisymmetrized wave function; N-electron Slater determinant. Week 12 Expectation value of ground-state energy Ee with the Slater determinant of an N-electron system. Week 13 Hartree-Fock equations obtained by minimizing Ee subject to the constraint that the spinorbitals are orthonormal. Week 14 Hartree-Fock-Roothaan equations: Hartree-Fock SCF procedure for molecular systems, in which each spatial wave function is expressed as a linear combination of basis functions; Selection of basis sets. Week 15 Interpretation of computer outputs of ab initio calculations; Final examination. |
| Prerequisites |
|
Ability to earn the credits of quantum chemistry I･II and structural chemistry offered for the undergraduate students of organic and polymer materials chemistry (or similar courses) is necessary. In addition to the time in the class, students are recommended to spend the standard amount of time as specified by the University on self-learning. |
| Required Text(s) and Materials |
| References |
| Handouts will be distributed. |
| Assessment/Grading |
| Final examination (50 %) and participation in discussion (50 %). |
| Message from instructor(s) |
| It is desirable that you understand the significance and limitation of chemical models simplifying the real systems as well as intend to avoid creating black boxes as much as possible. Every student who takes this course will be often asked for an opinion in the class and is expected to cultivate the ability of scientific explanation and discussion. |
