Zn(NO3)2•6H2O and AgNO3, respectively. UV irradiation of these two photoreactive compounds (1) and (3) resulted in the formation of two new coordination polymers [Zn(μ-OH2)(5-Me-1,3-bdc)(HT-bpbpcb)0.5]•H2O}n (2, HT-bpbpcb = 1,3-bis(2-pyridyl)-2,4-bis(3-pyridyl)cyclobutane) and [Ag2(5-Me-1,3-Hbdc)(HH-bpbpcb)][Ag(5-Me-1,3-bdc)(2,3'-bpe)]•H2O}n (4, HH-bpbpcb = 1,2-bis(2-pyridyl)-3,4-bis(3-pyridyl)cyclobutane)
两种光反应性配位聚合物[Zn(μ-OH2)(5-Me-1,3-bdc)(2,3'-bpe)]•H2O} n(1)和[Ag2(5-Me-1,基于水热法制备了3-Hbdc)(2,3'-bpe)2] [Ag(5-Me-1,3-bdc)(2,3'-bpe)]•H2O} n(3)不对称烯烃1-(2-吡啶基)-2-(3-吡啶基)-乙烯(2,3'-bpe)与辅助配体5-甲基-1,3-苯二甲酸(5-Me-1)之间的反应(3-H2bdc)分别存在Zn(NO3)2•6H2O和AgNO3。这两种光反应性化合物(1)和(3)的紫外线照射导致形成了两种新的配位聚合物[Zn(μ-OH2)(5-Me-1,3-bdc)(HT-bpbpcb)0.5]• H2O} n(2,HT-bpbpcb = 1,3-双(2-吡啶基)-2,4-双(3-吡啶基)环丁烷)和[Ag2(5-Me-1,3-Hbdc)(HH -bpbpcb)]
