We present a first-principles study of the structural, electronic, and optical properties of four conjugated polymers, poly p -phenylene PPP , poly 2,7-fluorene PF , poly 2,7-carbazole PC , and poly 2,7-borafluorene PBF , and of their isolated constituent molecules.

All the calculations were done using density-functional theory DFT with a plane-wave basis set, pseudopotentials, and local exchange-correlation energy. Resemblances in the atomic structures of the systems studied allow us to make correspondences between their wave functions near the Fermi energy.

In agreement with experimental data, we find smaller energy gaps for carbazole and borafluorene compared to biphenyl and fluorene, which is due to differences in the highest occupied molecular orbital HOMO or lowest unoccupied molecular orbital LUMO wave functions. Our calculations explain this experimental observation which is attributed to a change in the ordering of the last two valence bands between carbazole and its polymer.

The polarizations for the lowest electronic transitions are presented from the analysis of the wave functions' symmetries. We find excellent agreement between the calculated and available experimental data, validating the predictions made.

Since the discovery of the light emitting properties of the phenyl-based organic semiconductors in there has been a huge growth of interest in conjugated polymers. The potential device applications are enormous, ranging from optical switching to solar cells and light emitting devices. They are also active components in many important biological processes. Progress in our understanding of the fundamental physics of conjugated polymers, which provides a crucial underpinning to the technological applications, has also been large. This progress has been driven by experimental, theoretical and

Пришла пора действовать. Нужно выключить ТРАНСТЕКСТ и бежать. Она посмотрела на светящиеся мониторы Стратмора, бросилась к его письменному столу и начала нажимать на клавиши.

Девушка кивнула, и рыжие шелковистые волосы скользнули по ее плечам. Беккер молил Бога, чтобы это оказалось неправдой. - Рего… Но… Она пожала плечами и произнесла по-испански: - Девушке возле парка. Беккер почувствовал, что у него подкашиваются ноги.

Провал.
