Synthesis under Microwave Irradiation and Crystal Structure of 4-（3,4-Methylenedioxylphenyl）-6-methyl- 5-ethoxycaronyl-3,4-dihydropyrimidin-2（H）-one

1 INTRODUCTION Since Biginelli firstly reported the synthesis of 3,4-dihydropyrimidin-2(1H)-ones in 1893, this com- pound has been found to emerge as calcium channel blockers, antihypersive agents and a-antagonists[1]. Consequently, this Biginelli reacti…     

两个金属有机框架化合物对硝基芳香化合物在气/液相的荧光传感

制备了2个金属有机框架化合物[Cd_2(DDCPB)(DMF)_2(H_2O)]_n(CHD-1)和{[Zn_2(DDCPB)(DMA)_2]·DMA}_n(CHD-2)(H_4DDCPB=1,1′∶3′,1″-三联苯-3,3″,5,5″-四羧酸)。荧光测试表明:2个化合物均能在气/液两相中高效地选择性识别系列硝基芳香化合物(NACs)。溶液中NACs对2个化合物的荧光有较高的淬灭率,其淬灭常数可通过定量实验计算。CHD-1和CHD-2对溶液中的NACs显示出高选择性、优异的灵敏度和低检测限。基于2个化合物的薄膜检测对硝基苯(NB)和2-硝基甲苯(o-MNT)蒸气时也具有高灵敏度。此外,详细讨论了化合物的荧光传感机理。
