We design a flexible, amphiphilic LMWG consisting of donor and acceptor π-chromophores which self-assembles into a hydrogel and an organogel with different nano-morphologies. Different mechanisms of self-assembly evolve charge transfer (CT) emission in th

Five isostructural 1D porous coordination polymers (PCPs) with a general formula of {[M(L)(DMF)(H2O)]·1.5H2O}n [M = TbIII (1), EuIII (2), YbIII (3), NdIII (4) and ErIII (5)] have been synthesized using a flexible tripodal organic linker (L) and characterized. TbIII (1) and EuIII (2) PCPs exhibit metal-based green and red emission, respectively, whereas YbIII (3), NdIII (4) and ErIII (5) PCPs show near-infrared (NIR) emission. Doping EuIII in 1 in a precisely controlled stoichiometric amount leads to different mixed lanthanide PCPs, {[Tb1-xEux(L)(DMF)(H2O)]·1.5H2O}n (1a-1f) that show tunable emission including that of bright white light. The PCPs decorated with Lewis basic -O- binding sites make them potential candidates for the binding and selective sensing of traces of CuII ions, and this is illustrated for PCP 2 (limit of detection = 0.69 ± 0.02 ppm). The photoluminescence of 2 can be recovered by the introduction of a chelating ligand ethylenediaminetetraacetic acid (EDTA) without any structural disintegration, indicating the potential of the lanthanide PCPs for future sensing applications.
Synthesis and structures of three-and hexa-armed benzene derivatives featuring lateral benzoic ester and benzoic acid functions
Foerster, Sebastian,Seichter, Wilhelm,Weber, Edwin
experimental part, p. 939 - 946 (2011/10/11)
The new 1,3,5-tri-substituted and hexa-substituted benzoic methyl esters 1, 3 and benzoic acids 2, 4 have been synthesized. Single-crystal structure determinations of 1-3 are reported, which show specific molecular conformations and packings in the crysta
