A semiconducting supramolecular Co(ii)-metallohydrogel: an efficient catalyst for single-pot aryl–S bond formation at room temperature

Abstract

A monoethanolamine based Co(ii)-metallohydrogel can act as a Schottky barrier diode device and a catalyst for single-pot aryl–S bond formation at room temperature.

Metal–organic gels and their derived materials for electrochemical applications

“…The CoMEA hydrogel was produced from an aqueous solution of Co 2+ and monoethanolamine. 121 FESEM and TEM analyses revealed an interconnected hierarchical nano-ower architecture consisting of bers for the CoMEA gel. The semiconducting gel shows potential for application in SBD devices.…”

Triethylenetetramine-Based Semiconducting Fe(III) Metallogel: Effective Catalyst for Aryl–S Coupling

“…During the last few years, our group has been involved in metallogel-based research on fabrication of semiconducting devices . Besides, we have an aim to approach the multi-functional behavior of the metallogel system . Powered with the knowledge of transition-metal ion-directed catalysis toward synthetic organic chemistry, Fe­(III)-metallogel-based catalysis in organic synthesis has been targeted.…”

Cd-Based Metallohydrogel Composites with Graphene Oxide, MoS2, MoSe2, and WS2 for Semiconducting Schottky Barrier Diodes

“…Besides, the current era is concerned about the formation of supramolecular gels by use of low-molecular-weight gelators (LMWGs) for their prospects in materials science . The participation of transition-metal ions involving Mn, Fe, Co, Ni, Cu, and Cd with LMWGs introduces several additional functionalities like magnetic activity, redox activity, optical activity, catalytic activity, electrical conductivity, and so on. − ,, Among different transition metals, Cd­(II) is noteworthy in numerous scientific prospects including organometallic research, synthetic coordination chemistry, quantum dot, coordination polymer, and catalysis . Even so, the semiconducting property of a Cd­(II)-based soft gel system toward device fabrication is well recognized in literature .…”

“…The use of amine-based metallohydrogels for semiconducting applications has already been established. , Inspired by these thoughts, we have introduced hydrazine hydrate (N 2 H 4 ·H 2 O) as an extreme LMWG with cadmium­(II) acetate dihydrate to obtain a novel supramolecular Cd­(II) metallohydrogel (Cd-N 2 H 4 ). The semiconducting nature of our synthesized Cd-N 2 H 4 has been judged by exploring its optoelectronic and electrical properties through measurement of the optical band gap and electrical conductivity via the successful fabrication of a metal–semiconductor junction-based photosensitive Schottky diode (SD).…”
