We study the structural, electronic and transport property of bilayer blue phosphorus (BBP) by using the first-principles. Our results show that the band gap can be adjusted by different stacking structures of the BBP. We simulate the functional device based on AA-, AB-and AC-stacking BBP and the transport characteristics of the current-voltage curve with nonlinear competitive behavior are investigated. Of the three devices, AA stacking BBP has the highest conductivity. Under special bias, the currents of AB-and AC-stacking devices produce interesting competitive behavior. The transport characteristics behaviors of the BBP can be explained by the band structure, transport spectrum and molecular projected self-consistent Hamiltonian. We can control the change of current by adjusting the different contact modes of the BBP. The BBP with interesting electronic and transport properties are expected to have potential applications in nanoelectronics.

In this paper, the perfluoro aryl ether dendrons were synthesized by mesylate reaction, and using the dendron as a modifier to prepare a novel fluorinated polyhedral oligomeric silsesquioxane ( F-POSS) nano-particle bearing this fluorine-containing dendron. In this approach, the Williamson ether synthesis technique was used as the generation enhancement step. Second generation perfluorobenzyl alcohol dendron was obtained from active mesylated precursors. This mesylate actiation technology has the advantage of short reaction times in the subsequent steps and avoids chromatographic purifiction. Second genenriation dendron was then built by repitition of Williamson ether synthesis reaction of mesylate derivative. It is possible for this new nano-particle to be used in the modification of polymer materials to make the durable superhydrophobic and oilphobic surface functional materials with excellent self-cleaning properties.
