“…There has been much attention in organosilicon polymers composed of an alternating arrangement of an organosilicon unit and p-electron system, since they may be used as functionality materials [1], such as, for example, organic semiconductors [2] and hole-transporting materials [3]. In addition, an interest has been focused on these types of the polymers regarding their heat-resistant properties.…”

“…41) with reasonable molecular weights of 76-94 kDa (M w with a polydispersity of 2.5-3.8) were used as holetransport materials in combination with Alq 3 as emitter in a double-layer OLED setup [194]. The OLEDs showed the expected green light from Alq 3 emission after reaching the turn-on voltage.…”

In this chapter different types of conjugated organosilicon materials possessing luminescent and/or semiconducting properties will be described. Such macromolecules have various topologies and molecular structures: linear, branched and hyperbranched oligomers, polymers, and dendrimers. Specific synthetic approaches to access these structures will be discussed. Special attention is devoted to the role of silicon in these structures and its influence on their optical and electrical properties, leading to their potential application in the emerging areas of organic and hybrid electronics.

“…Almost all the - conjugated polymers are reported to be hole transport materials [36][37][38][39]. This attracted our interest in the positive-one-charge-doping effects on the - conjugated oligomers of a-g in Figure 1 (in the Figure 1 The oligomers with 30 atoms in the main chain studied in this paper.…”

The charge-doping effect on the geometric and the electronic structures of organosilicon oligomers nSi x (C=C) y + has been studied using density functional theory. Charge-doping can significantly lower the excitation energies. Interchain hole hopping mainly occurs between the -conjugated units. A doped nSi x (C=C) y + oligomer can undergo a structural rearrangement. The simulated UV/vis absorption peak of the rearranged structure is located at higher energy than the non-rearranged one. The hole transfer rate is significantly decreased if a doped molecule undergoes a rearrangement. These results offer a basis to explain previously observed experimental phenomena.
