Abstract
A new 5,11-dihydroindolo[3,2-b]carbazole-based bidentate ligand bearing two carboxylic groups has been synthesized in two steps and utilized for the construction of metal–organic coordination polymers for the first time. Two Zn containing coordination polymers with 2D and 3D structures were obtained. Both compounds display linker-based blue fluorescence.

A new 5,11-dihydroindolo[3,2-b]carbazole-based bidentate ligand bearing two carboxylic groups, (3,3′-(indolo[3,2-b]carbazole-5,11-diyl)dipropionic acid, H2icdc), has been synthesized in two steps and then used for the construction of two metal–organic coordination polymers, namely [Zn3(dmf)2(icdc)3]·4DMF (1) and [Zn2(dabco)(icdc)2]·4NMP·4H2O (2) (dabco = 1,4-diazabicyclo[2.2.2]octane, DMF = N,N-dimethylformamide, NMP = N-methyl-2-pyrrolidone). Compound 1 has a layered structure, while compound 2 has a 3D framework structure. Both compounds display linker-based blue fluorescence.
