Freestanding silicon nanoparticles (FS-nc-Si) have intriguing chemical and optical properties. The present contribution outlines known synthetic methodologies and protocols for surface functionalization. Recent advancements in tailoring the photoluminescence properties of FS-nc-Si and future research directions will be briefly discussed.
The title compound, C29H42, crystallizes from the melt as a triclinic crystal. The unit cell contains three crystallographically independent molecules. The three fluorene ring systems are oriented such that two non-equivalent ring systems related by a roto-translation are separated by a third ring system oriented orthogonally to them. The octyl chains of all three molecules are perpendicular to the fluorene ring system and force a 7.4 angstroms separation between the two coplanar molecules, thereby preventing molecular pi-stacking.
Small molecule and polymer organic light-emitting diodes (OLEDs) show promise of revolutionizing display technologies. Hence, these devices and the materials that render them functional are the focus of intense scientific and technological interest. The archetypical multilayer OLED heterostructure introduces numerous chemical and physical challenges to the development of efficient and robust devices. It is demonstrated here that robust, pinhole-free, conformal, adherent films with covalently interlinked structures are readily formed via self-assembling or spin-coating organosilane-functionalized molecular precursors at the anode-hole transport layer interface. In this manner, molecularly "engineered" hole transport and hydrocarbon anode functionalization layers can be introduced with thicknesses tunable from the angstrom to nanometer scale. These investigations unequivocally show that charge injection and continuity at the anode-hole transport layer interface, hence OLED durability and efficiency, can be substantially enhanced by these tailored layers.
