Synthesis, structure, and luminescent properties of oligothiophene-containing metal–organic frameworks [link]Paper  doi  abstract   bibtex   
Metal–organic frameworks (MOFs) based on Zn and functionalized bithiophene dicarboxylic acids are reported, [Zn2(L1)2(DMA)2·3 DMF]n (1), [Zn(L2)(DMA)2]n (2), [Zn(L3)(bpe)0.5]n (3), [Zn(L1)(bpe)·2 DMF]n (4), and [Zn3(L2)3(bpe)2·4 DMF · H2O]n(5) (H2L1 = 3,3'-diphenyl-2,2'-bithiophene-5,5'-dicarboxylic acid, H2L2 = 3,3'-dihexyl-2,2'-bithiophene-5,5'-dicarboxylic acid, H2L3 = 2,2'-bithiophene-5,5'-dicarboxylic acid, DMA = dimethylamine, DMF = N,N-dimethylformamide, bpe = trans-1,2-bis(4-pyridyl)ethylene). MOFs 1, 2, and 4 consist of 2-D 4-connected sheets while 3 and 5 are 3-D interpenetrated networks with pcu and (4,6)-connected seh topology, respectively. The emission spectra and lifetimes of 1–5 have been determined: 4 and 5 exhibit reduced emission relative to 1 and 2, respectively, attributed to energy transfer quenching by the bpe, whereas 3 does not exhibit a reduction in emission intensity. Solid state lifetime measurements of 1–5 show that the emission decays are similar to those of the constituent ligands.
