Self-assembly of T-shape 2H-benzo[d][1,2,3]-triazoles. Optical waveguide and photophysical properties

Abstract

T-Shaped 2H-benzo[d][1,2,3]triazole derivatives have been synthesized by Sonogashira coupling reactions under microwave irradiation.

Self‐Assembled Alkynyl Azoles and Benzoazoles as Colored Optical Waveguides

“…[30] It should be noted that the previously synthesized triazoles have a V-shape whereas the benzotriazoles adopt a T-shape. [30] It should be noted that the previously synthesized triazoles have a V-shape whereas the benzotriazoles adopt a T-shape.…”

“…[30] Furthermore, the introduction of methoxy substituents only affects the value of the HOMO and this leads to a decrease in the bandgap. The topologies of the Frontier Molecular Orbitals (FMO) are very similar in compounds 7 a-d.…”

Extended Alkenyl and Alkynyl Benzotriazoles with Enhanced Two‐Photon Absorption Properties as a Promising Alternative to Benzothiadiazoles

“…Reactions with air‐sensitive materials were carried out under an argon atmosphere. Compounds 1 a – d , 3 a , 3 c , and 3 d were prepared as reported in the literature . Flash chromatography was performed on silica gel (Merck, Kieselgel 60, 230–240 mesh or Scharlau 60, 230–240 mesh).…”

“…In addition to BTDs, our research in recent years has also focused on 2 H ‐benzo[ d ][1,2,3]triazole (BTz) as another benzoazole derivative. BTz is an interesting option to consider due to its excellent photophysical properties . Despite the fact that BTz has a less accepting core than that of BTD, this unit allows better functionality.…”

[5,6] Despite the fact that BTz has al ess accepting core than that of BTD, this unit allows betterf unctionality.I tis possible not only to introduce groups in positions 4a nd 7, but also to functionalize nitrogen at position 2. This affords modulation of the acceptor character and increasest he solubility of the compounds.…”
