Chemical Communications. :5842-5844. Abstract

We present a new concept for the design of a polymeric conducting material that combines the chemical versatility of an organic salt ( ionic liquid) with the morphological versatility of a biopolymer ( gelatin); the resulting 'ion jelly' can be applied in electrochemical devices, such as batteries, fuel cells, electrochromic windows or photovoltaic cells.

Photochromism of trans-4-(N,N-diethylamino)-2,4'-dihydroxychalcone, with formation of the photoproduct 7-(N,N-diethylamino)-4'-hydroxyflavylium, is promoted in the ionic liquid phase of a water/[bmim][PF6] biphasic system.

Parola, AJ, Lima JC, Pina F, Pina J, de Melo JS, Soriano C, Garcia-Espana E, Aucejo R, Alarcon J.  2007.  Synthesis and photophysical properties of dansyl-based polyamine ligands and their Zn(II) complexes, 2007. Inorganica Chimica Acta. 360:1200-1208. Abstract

The synthesis, potentiometric studies and photophysical properties of two new polyamine ligands (L1 and L2) possessing the dansyl chromophore were studied in aqueous 0.15 M NaCl. The compounds show the absorption and emissions bands characteristic of the dansylamide fluorophore and both present intramolecular excited state proton transfer at intermediate pH ranges. One of the ligands (L2) strongly coordinates Zn(II) leading to fluorescence quenching. A model compound (L3) of the dansyl moiety was also investigated. (c) 2006 Elsevier B.V. All rights reserved.
