In this paper,Calixarenes 5,11,17,23 tetrasulfonic acid, tetrasodium salt was synthesized by the reaction of calixarenes and H 2SO 4. The yield of the Calixarenes 5,11,17,23 tetrasulfonic sodiums was improved to 20%~30% using the method that the reactant (filitrated H 2SO 4) was dissolved in a little amount of NaCl saturated solution and then the water was volatilized at room temperature.
Two copper complexes with a new multi sulfur 1,2 dithiolene ligand, C (C=tetrabutylammonium, n Bu4N+; tetraphenylphosphonium, Ph4P+; cddt = 4a, 6, 7, 7a 5H cyclopenta 1,4 dithiin 2,3 dithiolate) have been synthesized and characterized by electrochemical studies, IR, EA, etc. The structure of (Ph4P) was determined by single crystal X ray analysis. The complex was crystallized in the triclinic, space group with the cell dimensions a=10.460(2)?, b=13.000(3)?,c=16.270(3)?, α=86.68(3)°,β= 71.92(3)°,γ=66.66(3)° and Z=2. R1=0.0548, wR2=0.1358 for 6786 independent reflections. The four S atoms surround the Cu atom core is a square planar environment.
