Carborane photochromism: a fatigue resistant carborane switch

Abstract

A dithienylethene molecule involving carborane clusters shows remarkable fatigue resistance and high contrast visual colour changes when irradiated with alternating ultraviolet and visible light. The fluorescence of this assembly can...

Poled polymers and their nonlinear optics

“…18(c), it can be attributed to the trans → cis photoisomerization reaction or ring-opening/closing reaction under light. Azobenzene 106,107 ( trans → cis photoisomerization), diarylethene, 108,109 spiropyrans 110,111 or dithienylethene are just the typical photochromic compounds 112,113 (photo induced ring-opening/closing).…”

Octanuclear Palladacycles with B(3)–H Bond Activation of o‐Carborane†

“…[ 2 ] Recently, the rapid development of carborane chemistry allows the design and synthesis of various carborane compounds as a kind of useful tools for supporting and stabilizing new‐type organometallic structures, for instance, carboranyl‐ligand‐supported supramolecular structure, [ 3 ] metallaoradicals, [ 4 ] borylenes, [ 5 ] coinage metal clusters, [ 6 ] tetrylones, [ 7 ] carborane‐containing luminophores. [ 8 ] It is worth noting that the possibility of assembling metallacycles by carboranyl ligand has revealed by the synthesis of p ‐carboranyl dithiamide supported metallacycles. [ 3 ] Because of the unique electronic structure and properties of carborane nuclei, such metallacycle structure could have special properties which are hardly found on analogues supported by common organic ligands and hence receive sustained attention.…”

A comparison of para, meta, and ortho-carborane centred non-fullerene acceptors for organic solar cells

“…10–17 Such properties can be finely tuned through the choice of conjugated substituent groups, and may result in responsivity to external factors such as thermal or mechanical stimuli, or exposure to solvent vapours. 18–27 Emissive carborane species have also been demonstrated as the photoactive component in organic light emitting diodes on several occasions. 28–32…”

“…[10][11][12][13][14][15][16][17] Such properties can be finely tuned through the choice of conjugated substituent groups, and may result in responsivity to external factors such as thermal or mechanical stimuli, or exposure to solvent vapours. [18][19][20][21][22][23][24][25][26][27] Emissive carborane species have also been demonstrated as the photoactive component in organic light emitting diodes on several occasions. [28][29][30][31][32] Examples of emissive carborane-containing species also include a number of conjugated polymers, with emissive properties depending on the selection of carborane isomer and substituent site, and a certain tuneability based on the selection of conjugated co-monomers.…”
