“…Furthermore, it was found that the mixing of 1a – c with NAP led to decreases in the fluorescence intensity of NAP with hypsochromic/blueshifts. The hypsochromic/blueshift and the decrease in fluorescence intensity indicated that NAP molecule formed host–guest inclusion complexes with calix[4]arene derivatives 1a – c [ 25 ]. Similarly, only a small decrease in fluorescence intensity of NAP upon the addition of monomeric analogue 2 was observed ( Figure 5 ), which indicates a weak interaction between 2 and NAP.…”

The inclusion complexes of a new family of nonionic amphiphilic calix[4]arenes with the anti-inflammatory hydrophobic drugs naproxen (NAP) and ibuprofen (IBP) were investigated. The effects of the alkyl chain’s length and the inner core of calix[4]arenes on the interaction of the two drugs with the calix[4]arenes were explored. The inclusion complexes of Amphiphiles 1a–c with NAP and IBP increased the solubility of these drugs in aqueous media. The interaction of 1a–c with the drugs in aqueous media was investigated through fluorescence, molecular modeling, and 1H-NMR analysis. TEM studies further supported the formation of inclusion complexes. The length of lipophilic alkyl chains and the intrinsic cyclic nature of cailx[4]arene derivatives 1a–c were found to have a significant impact on the solubility of NAP and IBP in pure water.

“…Since the investigation of calixarenes dealing with their syntheses, reactivity and a large variety of applications is very intense, [55][56][57][58][59][60][61][62][63][64][65][66][67][68][69][70] only selected examples of considered compounds are described in this review.…”

“…Many works deal with calixarene complexes, [150][151][152][153] among them complexes with metal ions, 152,153 are of a great importance so for recovery as well as for removal of toxic metals from industrial sewages. Having in view the ecological safety one should also point out studies concerning the nuclear waste management.…”
