Synthesis and Fluorescence Properties of Lower Rim Functionalized p-tert-Butyl Thiacalix[4]arenes Containing Anthraquinone and N,N-Diethylacetamide Fragments

Abstract

It was shown that the chemo-and stereoselective alkylation of the lower rim 1,3-disubstituted p-tert-butyl thiacalix [4] arenes in the cone conformation using 2-chloro-N,N-

Pillar[5]arenes with Morpholide and Pyrrolidide Substituents: Synthesis and Complex Formation with Alkali Metal Ions

“…The literature describes a variety of cage-like organic molecules with accessible internal cavities, e.g., crown ethers, [1] cyclodextrins, [2] cucurbiturils, [3] and calixarenes, [4][5][6] which can serve as hosts. In recent years, a new class of synthetic macrocycles -pillar[n]arenesattracts the interest of researchers.…”

Synthesis of p-tert-butylthiacalix[4]arenes functionalized with tris(2-aminoethyl)amine fragments at the lower rim and their interaction with model lipid membranes

“…[28][29][30] Cup-like structure of calix [4]arenes presents a suitable molecular platform for constructing on their basis threedimensional structures with wide range of cavity sizes, differing in number and type of binding centers, spatial arrangement of binding groups and also offers a possibility of forming asymmetric cavities and varying balance between rigidity and flexibility of receptor. [31,32] The current main objective is functionalizing the thiacalix [4]arene molecular platform with TREN fragments and their interaction with model lipid membranes.…”

Synthesis of Photo-Switchable Derivatives of p-tert-Butyl Thiacalix[4]arenes Containing Ethoxycarbonyl and 4-Amidoazobenzene Fragments in the Lower Rim Substituents

“…[20][21][22][23][24][25][26][27] The current main objective is the regioselective synthesis of partially substituted p-tert-butyl thiacalix [4]arene derivatives, with further functionalization to differently substituted thiacalix [4]arenes with predetermined spatial orientation of binding sites.…”
