Silver Hexafluoroantimonate‐Catalyzed Direct α‐Alkylation of Unactivated Ketones

A practically simple and direct α‐alkylation of unactivated ketones using benzylic alcohols has been achieved. The in situ formed acetals are the key for the success of the reaction. The catalyst, silver hexafluoroantimonate(V) (AgSbF₆) provides double activation by converting the ketone into an enol ether via acetal and generation of carbocationic center at the benzylic position of the benzylic alcohol. The alcohols include benzylic propargyl alcohols, cinnamyl alcohols, and diarylmethanols.

     

Twisted Crystalline Organic Semiconductor Photodetectors

Optoelectronic properties of anisotropic crystals vary with direction requiring that the orientation of molecular organic semiconductor crystals is controlled in optoelectronic device active layers to achieve optimal performance. Here, a generalizable strategy to introduce periodic variations in the out-of-plane orientations of 5,11-bis(triisopropylsilylethynyl)anthradithiophene (TIPS ADT) crystals is presented. TIPS ADT crystallized from the melt in the presence of 16 wt.% polyethylene (PE) forms banded spherulites of crystalline fibrils that twist in concert about the radial growth direction. These spherulites exhibit band-dependent light absorption, photoluminescence, and Raman scattering depending on the local orientation of crystals. Mueller matrix imaging reveals strong circular extinction (CE), with TIPS ADT banded spherulites exhibiting domains of positive or negative CE signal depending on the crystal twisting sense. Furthermore, orientation-dependent enhancement in charge injection and extraction in films of twisted TIPS ADT crystals compared to films of straight crystals is visualized in local conductive atomic force microscopy maps. This enhancement leads to 3.3- and 6.2-times larger photocurrents and external quantum efficiencies, respectively, in photodetectors comprising twisted crystals than those comprising straight crystals.     

Entropy generation analysis on forced and free convection flow in a vertical porous channel with aligned magnetic field and Navier slip

The entropy generation rate in a vertical porous channel with injection and suction walls and a uniform magnetic field provided at an angle $\xi$ to the flow direction is studied using an analytical perturbation technique in the presence of Navier slip and buoyancy force. The momentum and energy equations were solved for exemplary values of fluid convection's physical characteristics. Important parameters' impacts on adequate numbers are graphically portrayed and conveyed.     

Study of an Explosive-Driven Metal Plate

Equation of motion of an incompressible metal plate, accelerated by a plane detonation wave, has been solved for a general value of adiabatic exponent ß of detonation products to investigate its effect on terminal velocity of the plate. It has been found that the plate velocity increases with decreasing value of ß. The magnitude of this effect has been found sufficient to determine adiabatic exponent of detonation products from the measurement of flyer plate velocities at different C/M ratios. Velocities of metal plates, hurled by contact explosion of high density explosives, have also been measured with oscillographic technique by using an experimental setup which is insensitive to air shocks. The plate velocities measured by such an experimental setup have been found in good agreement with theoretical ones.
