“…The tetra-derivatives of azocalix [4]arene appended with 2alkylthiobenzenediazonium groups, 10.3A (60%), 10.3B (21%), 10.3C (51%) have been obtained with lesser yields as red solid when crystallized from THF/MeOH mixture. 92 Terta-azocalix [4]arene derivative having 10.3D and 10.3E are obtained in good yields of ~72-75% and these derivatives showed limited inhibitory activities against bacterial strains of S. epidermidis and E. faecalis bacteria. 91 However, the structure activity correlations among this category of azo-derivatives has been least understood.…”

In the broad area of supramolecular chemistry, the calix[n]arene provides a congenial platform for synthetic modifications, and further has been a highly studied system and thereby occupies a unique position among the supramolecular scaffolds. This is attributable to its pre-organised hydrophobic cavity, amenability to synthetic modifications to generate derivatives, presence of pre-organised ion binding cores along with reporter moieties both at its lower and upper rims. Such derivatizations lead to well defined conformations, and tunable functionalization at both these rims. Among various possible derivatizations, the synthetic strategies of those leading to cone conformation have been rationalized in this review article. In addition, some insights into the synthesis of calix[4]arene dimers and tubes, and a variety of different macrocyclic derivatives of the calixarene have also been taken into consideration. All the conjugated derivatives of calix[4]arene platform reported in this article have been provided with a relevance to highlight their application potential.
