Analytical applications of calixarenes from 2005 up-to-date

Preparation and Characterization of Bonded-Phases of Calixarene-Sulfonyl-Carboxamides in Partial-Cone Conformation for Determination of Salbutamol in Livestock by Nano-Mediated Bonded-Phases: Nano-Baskets of Calixarene in Partial-Cone Conformation

“…In the present work, the synthesis of eight derivatives of p-tert-calix [4] arene bearing di-[N-(X)sulfonyl carboxamide] and di-(1-propoxy) in partialcone conformation and the preparation of its bonded silica stationary phase were described [X= Phenyl (01,05), p-CH 3 Phenyl (02,06), p-OHPhenyl (03,07), p-NO 2 Phenyl (04,08)]. A new method for determination of salbutamol in the livestock meat samples was set up by using the new calix [4]arene-based column.…”

“…Eight nanobaskets of p-tert-calix [4]arene bearing di-[N-(X)sulfonyl carboxamide] and di-(1-propoxy) in partial-cone conformation were synthesized and were used to prepare bended phases of HPLC-UV. The new synthesized bonded-phases were characterized and optimized, the bonding interactions of solute and stationary phases were examined and the main interactions were reported.…”

“…In order to protect consumers, specific and sensitive methods for the identification and quantitation of salbutamol in meat and other food are required. Nano-baskets of calixarenes and calixcrowns are a versatile class of macrocycles, which have been subject to extensive research in development of many extractants, (using gas chromatograph, Teif Gostar Faraz Co.) transporters and stationary phases over the past four decades [4][5][6]. Functionalization of calix [4]arenes at both the upper rim and the lower rim has been extensively studied [7][8][9].…”

Functionalization of calix [4]arenes at both the upper rim and the lower rim has been extensively studied [7][8][9]. Attaching donor atoms to the lower rim of a calix [4]arene can improve the binding strength of the parent calixarene dramatically [10][11][12].…”

“…Functionalization of calix [4]arenes at both the upper rim and the lower rim has been extensively studied [7][8][9]. Attaching donor atoms to the lower rim of a calix [4]arene can improve the binding strength of the parent calixarene dramatically [10][11][12]. Calixarene-bonded stationary phases are preferable to the use as mobile-phase additives, because the UV detection of analytes is prevented by strong absorbance of calixarenes [13][14][15].…”
