Spectroscopic evidence for enantiomeric recognition of properly modified amino acids through the cyclodextrin assisted formation of polymer like self-assemblies is presented. The requirements for the formation of these assemblies through aromatic pi-pi stacking are discussed. It is suggested that this approach can be used for enantiomeric separation of chiral compounds that contain both electron-rich and electron-poor moieties. (C) 2004 Elsevier Ltd. All rights reserved.

A novel organic nonlinear optical (NLO) material, L-alaninium succinate, was synthesized by the standard method. The synthesized material was purified by repeated recrystallization. Single crystals were grown by slow evaporation technique using water as solvent. The grown crystals were characterized by FTIR, FT-NMR and UV-vis-NIR techniques. The second harmonic generation (SHG) from the material was confirmed using Nd:YAG laser which shows that LAS has 23% SHG efficiency of that of the standard KDP. The UV-vis-NIR transmittance was recorded in the range from 190 to 1100 nm. In this study, the lower cut-off is shifted towards UV region (190 nm) which shows that LAS has good transmittance in region from 190 to 1100 nm and it makes LAS for SHG. Functional groups present in the grown crystal were identified using FT-IR spectrum which gives confirmation of NH(3)(+) ion in LAS. The chemical structure of L-alaninium succinate was established by FT-NMR technique. Crown Copyright (C) 2008 Published by Elsevier B.V. All rights reserved.
