A multifunctional organometallic switch with carbon-rich ruthenium and diarylethene units

Abstract

The perturbation of a dithienylethene system by a ruthenium carbon-rich system, and vice versa, was used to reach a unique and sophisticated light- and electro-triggered multifunctional switch featuring multicolor electrochromism, electrocyclization at remarkably low voltage, and photo/electro tuning of electronic communication.

Highly Efficient Visible‐Light Driven Photochromism: Developments towards a Solid‐State Molecular Switch Operating through a Triplet‐Sensitised Pathway

“…[9] Of particular interest are the complexes [ [10] and [ClRuA C H T U N G T R E N N U N G (dppe) 2 -CC-DTE-CC-RuA C H T U N G T R E N N U N G (dppe) 2 Cl] (dppe = Ph 2 PCH 2 CH 2 PPh 2 ), [11] which display both electrochromism and electrocyclisation. Recently, Branda and Wolf [12] have shown that in the mono-platinum complex…”

A simple synthesis of trans-RuCl(CCR)(dppe)2 complexes and representative molecular structures

“…The use of isolated [RuCl(dppe) 2 ] + ([2] + ) salts as an entry to acetylide complexes trans-RuCl(C"CR)(dppe) 2 and related compounds has recently begun to attract attention [12,14,27,34,35,57,58]. In this contribution, we detail a convenient preparation of acetylide complexes 3 from trans-1 that takes advantage of the ready abstraction of a chloride ligand from trans-1 by AgOTf in dichloromethane to give the key reagent [2]OTf.…”

A single-molecule multicolor electrochromic device generated through medium engineering

“…Transition metals based on metal-organic complex multicolor electrochromic materials exhibit attractive properties, such as high stability and chemiluminescence. 16 However, the expense and scarcity of the precious metals, such as ruthenium, 15,16 osmium 17 and iridium, 18 limit their practical applications. Polymeric multicolor electrochromic materials with different electrochromic activation units [19][20][21] possess the advantages of easy processing, diverse resources and facile color tunability.…”

“…Because the realization of a multicolor switch is preferred in the majority of their applications in displays, [4][5][6][7][8][9][10] various electrochromic materials including polymers, 11,12 small organic molecules 13,14 and metal-organic complexes, 15 and technologies aimed at multicolor switches have been intensively explored. Transition metals based on metal-organic complex multicolor electrochromic materials exhibit attractive properties, such as high stability and chemiluminescence.…”

“…Keywords: electrochromic materials; laminated electrodes; microenvironment; multicolor devices; solvatochromic materials INTRODUCTION Owing to the increasing demand for low-power, ultrathin, flexible electronic displays, organic electrochromic materials 1-3 have become a research focus because of their distinct merits: low weight, high contrast, wide viewing angle, flexibility and the potential for low power consumption. Because the realization of a multicolor switch is preferred in the majority of their applications in displays, 4-10 various electrochromic materials including polymers, 11,12 small organic molecules 13,14 and metal-organic complexes, 15 and technologies aimed at multicolor switches have been intensively explored.
