Resolution of Enantiomers of Novel C2‐Symmetric Aminobisphosphinic Acids via Diastereomeric Salt Formation With Quinine
Authors: Kaboudin Babak , Faghihi Mohammad Reza , Kazemi Foad , Yokomatsu Tsutomu 
Published: October 2014

AbstractC2‐symmetric N,N‐bis(phosphinomethyl)amines were prepared by the thermal reaction of aromatic aldehydes with ammonia and hypophosphorus acid as previously described. Both enantiomers of C2‐symmetric N,N‐bis(phosphinomethyl)amine were obtained in a high enantiomeric purity through the diastereomeric salt formation with (–)‐quinine, and subsequent fractional crystallization. X‐ray crystallographic analysis of one of the diastereomeric salts clearly revealed that (–)‐quinine could be an efficient resolving agent for obtaining the single enantiomer (R,R)‐N,N‐bis(phosphinomethyl)amine.

Manipulation and Orientation of Zeolite L by Using a Magnetic Field
Authors: Fibikar Sandra , Luppi Gianluigi , Martínez‐Junza Victor , Clemente‐León Miguel , De Cola Luisa 
Published: October 2014

AbstractA simple approach for the functionalization of cylindrically shaped zeolite L crystals with iron oxide magnetic nanoparticles is reported. These functionalized zeolites can be aligned very easily by applying a magnetic field in solution, on different substrates, and in a polymeric matrix. The aligned zeolite loaded with fluorescent dyes are anisotropic in both absorption and fluorescence owing to the linear arrangement of the channels and the restricted rotation of the molecules inside the channels. These findings can be applied on polymeric matrices, such as poly[3‐3′(vinylcarbazole)].
Azacrown Ethers from Mustard Carbonate Analogues
Authors: Aricò Fabio , Udrea Ilina , Crisma Marco , Tundo Pietro 
Published: October 2014

AbstractPolycondensation of a nitrogen mustard carbonate analogue with aromatic diols under dilution conditions affords a series of azacrown ethers previously not easily accessible as they require multistep synthesis including protection, purification, cyclization and methylation. This novel synthesis relies upon the anchimeric effect of the nitrogen mustard carbonate and it does not require the use of any base.
Electron‐Acceptor‐Dependent Light Absorption, Excited‐State Relaxation, and Charge Generation in Triphenylamine Dye‐Sensitized Solar Cells
Authors: Li Renzhi , Zhang Min , Yan Cancan , Yao Zhaoyang , Zhang Jing , Wang Peng 
Published: October 2014

AbstractBy choosing a simple triphenylamine electron donor, we herein compare the influence of electron acceptors benzothiadiazole benzoic acid (BTBA) and cyanoacrylic acid (CA), on energy levels, light absorption, and dynamics of excited‐state evolution and electron injection. DFT and time‐dependent DFT calculations disclosed remarkable intramolecular conformational changes for the excited states of these two donor–acceptor dyes. Photoinduced dihedral angle variation occurs to the triphenylamine unit in the CA dye and backbone planarization happens to conjugated aromatic blocks in the BTBA dye. Femtosecond spectroscopic measurements suggested the crucial role of having a long excited‐state lifetime in maintaining a high electron‐injection yield because a reduced driving force for a low energy‐gap dye can result in slower electron‐injection dynamics.
