prepare polyurethane NLO materials. The chemical structure of the chromophores and polyurethanes was characterized by 1H-NMR, FT-IR and UV-Vis spectroscopy. Thermal and nonlinearoptical activity characterizations of the chromophores and polyurethanes IPDI-1 and IPDI-2 were carried out. Both the chromophores and the polyurethanes NLO materials possessed relatively high thermalstability. The chromophores

An efficient one-pot preparation of (dialkylaminobenzyl)triphenylphosphonium salts directly from dialkylbenzenamine is described. The one-pot procedure proceeds quickly in high yields and allows the synthesis of useful reagents for Wittig reaction. Their potential is illustrated by the synthesis of a bolaamphiphilic fluorophore of interest for biological membrane imaging.
