Two ternary Cd(II) metal-organic frameworks [Cd4(L)2(2,6-NDA)4·5H2O]n (1) and [Cd(L)0.5(1,8-NDA)·0.75H2O]n (2) (L = 1,4-bis(1-(piperidin-4-ylmethyl)-1H-benzo[d]imidazole-2-yl)butane, 2,6-H2NDA = 2,6-naphthalenedicarboxylic acid, 1,8-H2NDA = 1,8-naphthalenedicarboxylic acid) were synthesized based on the L and two isomeric naphthalene dicarboxylic acids. 1 And 2 exhibit a 3D 4,4T11 and a 2D 3,4L13 network, resp. Both 1 and 2 show remarkable thermal stability and can be used as difunctional fluorescence sensors for Fe3+ and enrofloxacin via a fluorescence quenching process with high sensitivity and selectivity. In addition, the fluorescence sensing mechanism was discussed in detail. This study involved multiple reactions and reactants, such as 1-Ethyl-6-fluoro-4-oxo-7-(piperazin-1-yl)-1,4-dihydroquinoline-3-carboxylic acid (cas: 70458-96-7Computed Properties of C16H18FN3O3).
1-Ethyl-6-fluoro-4-oxo-7-(piperazin-1-yl)-1,4-dihydroquinoline-3-carboxylic acid (cas: 70458-96-7) belongs to piperazine derivatives. Piperazine causes primary dermal irritation and skin burns at high concentrations. Piperazine also causes eye irritation in humans. Although many piperazine derivatives occur naturally, piperazine itself can be synthesized by reacting alcoholic ammonia with 1,2-dichloroethane, by the action of sodium and ethylene glycol on ethylene diamine hydrochloride, or by reduction of pyrazine with sodium in ethanol.Computed Properties of C16H18FN3O3
