Abstract
A new family of non-ionic amphiphilic dendro-calix[4]arene bearing hydrophilic branched substituents at the upper rim and lipophilic alkyl chains at the lower rim was designed and synthesized. Micelles of various sizes are obtained due to the amphiphilic nature of the calix[4]arene derivatives in aqueous medium. The amphiphilic calix[4]arene derivatives effectively load hydrophobic dye such as alizarin yellow via secondary interactions such as hydrogen bonding and π-π stacking. The length of alkyl chain and the intrinsic cyclic nature of calixarene scaffold have shown a significant impact on the transport potential of all amphiphiles.

Catalytic C-H bond activation as a tool for functionalization of heterocycles
The major topic is the functionalization of heterocycles through catalyzed C-H bond activation. The strategies based on C-H activation not only provide straightforward formation of C-C or C-X bonds but, more importantly, allow for the avoidance of pre-functionalization of one or two of the cross-coupling partners. The beneficial impact of ...read more
