dc.description.abstractDisplay technology has become a vital and ubiquitous part of our daily life. Undoubtedly, today’s technologically minded society is living in the era of the digital image. After high resolution and efficiency could successfully be realized, the major trends in display technology now aim towards achieving high color purity for natural looking display colors. Organic light-emitting diodes (OLEDs), as one strong contender for high performance displays and lighting, have been undergoing tremendous industrial and commercial development. Despite the great progress, though, there is still space for improvement, especially in the case of blue light emitting devices. Blue OLEDs are always challenging, since they traditionally suffer from low efficiencies and lifetimes. Both, novel materials and device architectures, are driving ongoing developments while still always aiming to lower the overall costs. In a continual effort to search for robust materials for blue devices, small molecules (SMs) and polymers, are shown to be promising candidates. In this thesis is presented the results of the detailed study of photophysical and electroluminescence (EL) properties in the case of thin films based on blends of the conjugated polymer Poly(9,9-di-n-octylfluorenyl-2,7-diyl) (PFO) and the of novel SMs; 4,4'-(anthracene-9,10-diyl)bis(N,N-bis(4-methoxyphenyl)aniline) (TPAA) and 4,4'-(pyrene-1,6-diyl)bis(N,N-bis(4-methoxyphenyl)aniline) (TPAP). Finally, devices based on these systems are optimized step by step as a solution processable emissive layer (EML), for applications in sky blue OLEDs.
