IrAu<sub>12</sub> superatom modified by chiral diphosphines: doping-induced enhancement of chiroptical activity
نویسندگان
چکیده
Chiroptical activities of Au 13 superatom modified with chiral ligands were enhanced by doping an Ir atom at the center core. The IrAu 12 exhibited brighter circularly polarized luminescence than superatom.

Chiroptical inversion induced by sandwiching units in chiral polythiourethane.
Chiroptical behavior of a hydrogen-bond-regulated chiral polythiourethane segment was inversed by sandwiching sterically demanding segments in copolymers prepared by cationic ring-opening copolymerization of chiral cyclic thiourethanes derived from L-serine.
متن کاملChiroptical Measurement of Chiral Aggregates at
The centrifugal liquid membrane (CLM) cell has been utilized for chiroptical studies of liquid-liquid interfaces with a conventional circular dichroism (CD) spectropolarimeter. These studies required the characterization of optical properties of the rotating cylindrical CLM glass cell, which was used under the high speed rotation. In the present study, we have measured the circular and linear d...
متن کاملEnhancement of p-type doping of ZnSe using a modified „N¿Te...d -doping technique
Delta doping techniques have been investigated to enhance the p-type doping of ZnSe. Tellurium was used as a codopant for improving the nitrogen doping efficiency. The net acceptor concentration (NA2ND) increased to 1.5310 18 cm using single d doping of N and Te ~N1Te!, while it was limited to 8310 cm by d doping of N alone. A promising approach was developed in which three consecutive d-doped ...
متن کاملChiral ferrocenyl diphosphines for asymmetric transfer hydrogenation of acetophenone
The synthesis of new optically pure ferrocenyl diphosphines have been realized from (R)-(+)-N,Ndimethylaminoethylferrocene. Particularly, dissymmetric ferrocenyl diphosphines have been synthesized. The diphosphines have been used as ligands in asymmetric transfer hydrogenation of acetophenone in the presence of Ru catalysts. © 2006 Elsevier Science.

متن کاملSpeech Enhancement by Modified Convex Combination of Fractional Adaptive Filtering
This paper presents new adaptive filtering techniques used in speech enhancement system. Adaptive filtering schemes are subjected to different trade-offs regarding their steady-state misadjustment, speed of convergence, and tracking performance. Fractional Least-Mean-Square (FLMS) is a new adaptive algorithm which has better performance than the conventional LMS algorithm. Normalization of LMS ...
