Synthesis of elongated cavitands via click reactions and their use as chemosensors

The Role of Weak Interactions in Supramolecular Compounds: A Synthetic and Theoretical Study of Novel Elongated Cavitands

“…As it had already been described in our previously published paper CuAAC reactions can be applied for decorating a cavitand scaffold . Formerly, the reaction of tetraethynylcavitand and simple organic‐azide compounds resulted in triazole ring containing deepened cavitand structures.…”

“…Deepening the inner cavity was mainly accomplished by conventional organic reactions,, nevertheless homogeneous catalytic cross‐coupling reactions were meagerly employed as well ,. We formerly developed some novel synthetic procedures for the molecular enlargement of cavitands using the palladium‐catalyzed Stille‐coupling, Suzuki‐Miyaura, Sonogashira and aminocarbonylation reactions as well as copper(I)‐catalyzed azide‐alkyne cycloadditions (CuAAC) . Beside the simplicity, the excellent reaction efficiency makes the latter'click’ reactions frequently employed in the field of organic synthesis .…”

Synthesis and Electrochemical Properties of the Tetraferrocenyl‐Cavitand in Dimethyl Formamide Solvent Using Platinum and Carbon Working Electrodes

“…Basic books and papers can be consulted for finding methods for investigating properties of electrode processes of different species [17][18][19][20][21].…”

“…The obtained results were compared. The structure of new, home synthesized cavitand molecules [17] and their supramolecular interaction with different guest species have been studied in our laboratories by luminesce spectroscopic and theoretical chemical methods. Along these studies a tetraferrocenyl-cavitand host molecule has been synthesized from tetraethynylcavitand through a fourfold copper(I)-catalyzed alkyne cycloaddition (CuAAC, so called clickÀreaction) using ferrocenylmethyl azide as coupling partner.…”

Electronic Structure of Ferrocene-Substituted Cavitands: A QTAIM and NBO Study

“…However, in the ansa-bridged free chromocene the rings are unable to relax to a near parallel structure, therefore the triplet state is of less advantage [11]. The resorcin [4]arenes and the related cavitands are macrocyclic compounds consisting of multiple aromatic rings connected by different linkers [12]. Cavitands are known to offer excellent points of departure for the construction of large bowl-shaped molecular entities possessing a well-formed hydrophobic cavity.…”
