摘      要：In the present work,a zinc-based metal-organic framework{[Zn(ddpd)_(0.5)(bipy)_(0.5)]·H_(2)O]}_(n)(1-Zn)(where ddpd=2,5-di(2 ,4 -dic arboxylphenyl)-1,4-difluorobenzene,bipy=4,4-bipyridine)was synthesized by a solvothermal *** 1-Zn features a threedimensional(2,4,6)-connected network with{4^2.6^2.8^2}_(2){4^4.6^6.8^5}{6}***,without the assistance of other reagents,complex 1-Zn not only exhibited an exceeded 95%photodegradation efficiency for rhodamine B(Rh B),methyl blue(MB)and methyl orange(MO)within 40 min,but also showed high stability and *** addition,free radical quenching experiments and electron spin resonance(ESR)spectroscopy verified that the main active species in the photodegradation process were·O_(2)^(-)and OH,and a more indepth degradation mechanism was further elucidated by density functional theory(DFT)calculations.
