A discotic triphenylene dimer as organic hole transporting material for electroluminescence devices

Oligotriphenylene Nanofiber Sensors for Detection of Nitro‐Based Explosives

“…Conjugated polycyclic aromatic hydrocarbons (PAHs) are well‐known for exhibiting the ability to self‐assembly into 1D nanostructures through strong π − π stacking interactions 5–10. Triphenylene represents the smallest example of an all‐benzenoid PAH,11–13 and its derivatives exhibit unique electro/photoluminescence,14, 15 charge‐carrier mobility,16–18 energy migration,19, 20 and thermal and chemical stability 21, 22. Triphenylene‐based materials have thus emerged as one of the leading candidates for the fabrication of low‐dimensional electronic devices such as photoconductors,16, 23 light‐emitting diodes,21, 22, 24 and discotic liquid crystals 25, 26.…”

Synthesis and liquid crystal properties of triphenylene liquid crystals bearing polymerisable acrylate and methacrylate groups

“…Organic small molecules can often be processed by thermal evaporation to fabricate thin films, but this method has drawbacks of cost. Our early work found that discotic dimers having large enough molecular architecture facilitated good film-forming properties and were suitable for cheap solution processing [22]. Fabrication of films from solution was considered suitable for polymers rather than low molecular weight materials and the process was demonstrated in OLED fabrication [22].…”

Fabrication of films from solution was considered suitable for polymers rather than low molecular weight materials and the process was demonstrated in OLED fabrication [22]. A number of dimers [23][24][25], trimers [26], and triads [27] have been synthesized for this purpose.…”

Synthesis of unsymmetric triphenylene discotic liquid crystals with a semi-fluorinated chain and the influence of fluorophobic effect on mesogenic behavior

“…They are chemically and thermally stable and possess high charge carrier mobility and offer tremendous potential applications [4][5][6][7][8] . Triphenylene DLCs have been extensively studied as one-dimensional conductors [9] , photoconductors [10] , light-emitting diodes [11] , gas sensors, and LC displays [13] . Triphenylenes with different lengths of soft chains, both hydrophilic and hydrophobic peripheral chains [14,15] , hydrogen bonding substituents [16] , perfluorinated chains showing fluorophilic and fluorophobic effect [17][18][19][20][21] , metallic substituents [22] and polymerizable functional groups [23,24] have been exploited.…”
