Syntheses and photoluminescent properties of four zinc coordination polymers based on 1,4-bis[2-(4-pyridyl)ethenyl]-2,3,5,6-tetramethylbenzene and aliphatic dicarboxylates

Four coordination polymers [Zn(AZA)(1,4-bpetmb)0.5]n (1), [Zn(PIA)(1,4-bpetmb)]n (2), [Zn(H2O)(ADA)(1,4-bpetmb)]n (3) and [Zn(MUA)(1,4-bpetmb)]n (4) have been prepared by using of different aliphatic dicarboxylates. Their thermal stability and photoluminescent properties were also investigated.
