520 $a The work presented here describes the chemistry and applications of functional oligomers and polymers in terms of new aspects with regard to procedures, synthesis, and applicability. Chapter one is a general introduction on functional oligomers and polymers and the field of Organic Light Emitting Devices (OLEDs).
520 $a Chapter two describes synthesis and properties of functional polymers with pendant charge transporters. Significance of glass transition temperature on charge transport is probed by using these materials as hole transporters in an OLED.
520 $a Small molecules and conjugated polymers have been projected as host materials in phosphor dye doped OLEDs. In chapter three, triplet quenching between phosphor dyes and different host materials is studied. The study highlights an important criterion that needs to be considered when designing phosphor doped OLEDs. In order to fabricate highly efficient phosphor doped OLEDs, host materials with high triplet energy need to be used.
520 $a The concept of n-doping of electron transport layer (ETL) materials is useful in lowering the barrier for electron injection and increasing their conductivity. Chapter four describes this concept for OLEDs with an ETL based on a fluorene oligomer doped with a crown ether which showed dramatic improvements in brightness and quantum efficiency compared to undoped device.
520 $a The problem of phase segregation in phosphor doped conjugated polymer based OLEDs was addressed in chapter five by using a new organometallic complex. Covalently linked oligofluorene-organometallic complexes with polarity similar to the polymer were designed and evaluated as dopants in conjugated polymer based OLEDs. Microscopy images of doped polymer films indicate no evidence for any phase segregation.
520 $a Chapter six describes the kinetics, synthesis and characterization of polyfluorene based on Ni(0) based yamamoto coupling. The kinetics provided valuable insight for the synthesis of end functional polymer.
