Toward systematic understanding of diversity of electronic properties in low-dimensional molecular solids

Article Abstract:

Research activities in conducting molecular solids are carried out through collaborations between condensed matter physicists and chemists who used to live in 'momentum space' and 'real space', respectively. It is indicated that electrons in molecular solids are just the same as those in traditional metals and semiconductors, but the electronic states in molecular solids are based on molecular orbitals in contrast to the atomic orbitals.

Sigma and Pi-electron delocalization: Focus on substituent effects

Article Abstract:

Pi-electron delocalization is associated with many different phenomena where the most typical is aromatic character of cyclic pi-electron systems. Reactivity of pi-electron systems is also related to pi-electron delocalization during the process of polarization of the electron structure due to the approaching charged reagent.

Conjugated polymers and aromaticity

Article Abstract:

The consequences of bond length alteration and the highest occupied molecular orbital (HOMO) lowest occupied molecular orbit (LUMO) separation for smaller and very large aromatics are discussed. Conjugated polymers, which exist in the large N regime, offer interesting problems in aromaticity.
