A family of azoquinoline derivatives: Effect of the substituent at azo linkage on thermal cis-trans isomerization based on an experimental and computational approach

Multiple control of azoquinoline based molecular photoswitches

“…S25-S27 †). Among azoarenes with six-membered heterocycles that have been reported, E-1 has comparable bidirectional switching efficiency and thermal stability, [41][42][43][44][88][89][90] but the photoisomerization rate is lower than that of representative azoarenes with ve-membered pyrazoles that are nearly quantitatively switchable. 29,30 Photoinduced E / Z (82% Z isomer) and Z / E (85% E isomer) isomerization of E-2 in CDCl 3 was also attained.…”

“…[40][41][42] Azoquinoline has a phenyl directly attached to the azo group, but with an adjacent fused pyridyl group, which makes it intermediate in nature between azobenzene and azoheteroarene. In this context, photoinduced E / Z isomerization and thermal Z / E isomerization of azo compounds derived from hydrogenated quinolines and 8-quinolinols have been explored, 43,44 but the direct use of quinoline moieties as azo photoswitches is rarely reported.…”

A DFT study on the isomerization mechanism of azobenzene derivatives on silicon substrates

“…2 Many studies have shown that trans-AB is more stable than cis-AB due to its approximately planar structure. [3][4][5] There are convertible isomers of azobenzene derivative molecules, and they are potential candidates for molecular switches. 6 There are potential applications for azobenzene molecules in the fields of molecular scissors, 7-10 molecular switches, [11][12][13][14][15] optical information storage, [16][17][18][19][20][21] molecular machines, [22][23][24][25][26] nanolithography, [27][28][29][30] optical method-based gas sensors, 31,32 and other fields.…”
