Synthesis and characterization of luminescent conjugated organoboron oligomers and macrocycles

Conjugated molecules have been explored as an important class of organic materials that are of paramount interest in organic electronics, such as organic light emitting diodes (OLEDs), organic field-effect transistors (OFETs) and organic solar cells. Although current studies frequently concentrate on conjugated polymers, small molecules are attractive in that they allow for facile fine-tuning of the HOMO and LUMO energy levels, which is crucial for enhancement of the overall performance of organic devices. Functionalization of conjugated organic systems with main group elements represents an active research area of current interest in the chemistry and matarial science community. One of the most often employed elements is the electron-deficient boron that features an empty p orbital that opens up a pathway to overlap with π orbitals of attached aryl groups. This interaction leads to unusual optical and electronic properties for organoborane compounds. The focus of this thesis is on the investigation of well-defined organoborane oligomers and macrocycles.Ph. D.Includes bibliographical referencesIncludes vitaby Pangkuan Che
