Steric Constitution of Diphenylethane Analogues

Steric self-assembly of laterally confined organic semiconductor molecule analogues.

Self-assembly of planar molecules can be a critical route to control morphology in organic optoelectronic systems. In this study, Monte Carlo simulations were performed with polygonal disc analogues to planar semiconducting molecules under confinement. By examining statistically the molecular density and configurations of such analogues, we have observed that the symmetry of the confining mediu...

meso-1,2-bis(methylazo)-1,2-diphenylethane.

The title compound, meso-1,2-bis(methyldiazenyl)-1,2-diphenylethane, C16H18N4, is arranged in a disordered manner around an inversion point. The N-N atom distances in the azo group of 1.192 (8) and 1.195 (8) A, and the C-C atom distances in the ethylene moiety at 1.512 (8) and 1.503 (8) A in the two models [refined to 51.7 (6) and 48.3 (6)% occupancies] were not significantly different.

Steric Stabilization

Steric stabilization by polymers adsorbed on inorganic particle surfaces is gaining more and more attention in both industry and academia because it plays an important role in stabilizing colloidal dispersions. In this review, basic concepts and some related topics about steric stabilization are introduced. In addition the application of steric stabilization in dispersing ceramic particles in n...

Preparation of the Phencyclidine Analogues (Part II)

Using a-tetralone, as starting material, a series of phencyclidine analogues were synthesized. This ketone was reacted separately with ethylmagnesium bromide, P-methoxyphenylmagnesium bromide and P-methylphenylmagnesium bromide. The resultant alcohols were treated with a suspension of NaN3 and CCl3COOH in CHCl3. The azides were subsequently...
