摘　　要：A series of p-tert-butylcalix[4]arene 1,3-distal and monosubstituted semicarbazones and thiosemicarbazones was preparedd by acid catalyzed condensation reaction of active calixarene aldehydes with semi- carbazide and thiocarbazide in methanol. One representative single crystal was determined by X-ray dirraction method, which shows that calixarene exists in cone configuration and intramolecular hydrogen-bands exist in the crystal.A series of p-tert-butylcalix[4]arene 1,3-distal and monosubstituted semicarbazones and thiosemicarbazones was preparedd by acid catalyzed condensation reaction of active calixarene aldehydes with semi- carbazide and thiocarbazide in methanol.
