A well explained summary of molecular orbital theory covered in the first term of 1st year Durham university. This includes adding and subtracting atomic orbitals to form molecular orbitals, and molecular orbital diagrams. All relevant definitions are included, and all relevant diagrams are included.

Control of electronic properties in organic semiconductor materials is essential for electro-optical applications such as field-effect transistors, light-emitting diodes, and photovoltaic devices. This work is focused on two systems that highlight different approaches for the manipulation of electronic properties: (I) the development of electrondeficient (n-type) materials by selective lowering of ELUMO and (II) low energy gap materials by controlling both ELUMO and EHOMO. To specific...
