Synthesis of open chain crown ethers with isopropylidene hydrazide as terminal group and complexes of rare earth nitrate;

Three open chain crown ether complex with thioic schiff base were synthesized by condensation of diaromatic aldehyde with open chain crown ether and4-allyl-3-thioicsenicarbazide.

A novel open chain crown ether 2,6 di (8' quinolinoxy methyl) 4 methyl anisole was synthesized and characterized by elemental analysis, IR, 1HNMR and MS.

Syntheses, Characteration and Properties of Organic-Inorganic Coordination Compounds Generated from Acyclic Polyether-bridged Ligands;

In the presence of NaH and in DMF, the acyclic crown ethers 1a and 1b were synthesized by the reaction of di - or triethyleneglycol ditosylate and o - methoxymethoxybenzyl alcohol, which was obtained from salicylaldehyde via the protection of the hydroxyl group with chloromethyl methyl ether followed by the reduction of the formyl group with NaBH4.

In order to study the composition and the fluorescence properties of the complexes of amide-based open-chain crown ether containing the structure of 1,1’-binaphthyl,a amide-based open-chain crown ether and its five rare earth complexes were synthesized.

In order to study the composition and the fluorescence properties of the complexes of amide-based open-chain crown ether containing the structure of 1,1 -binaphthyl,N,N -dibenzyl-l,l -dinaphthyl-2,2 -bis (oxaacetamide) and its five rare earth complexes were synthesized.

An amide-based open-chain crown ether with the structure of 1,1\'-binaphthyl,N,N,N\'-tribenzyl-1,1\'-dinaphthyl-2,2\'-bis(oxaacetamide)and its four rare earth complexes were synthesized.

A new podand compound o- Bis (8'- quinolyloxy) ethyleneoxyl benzene was prepared for the first time .
