Carmen; Peon, Jorge published an article in 2021. The article was titled 《Two-photon induced isomerization through a cyaninic molecular antenna in azo compounds》, and you may find the article in Chemical Communications (Cambridge, United Kingdom).Reference of Methyltriphenylphosphonium bromide The information in the text is summarized as follows:
We present a new design for non-linear optically responsive mols. based on a modular scheme where a polymethinic antenna section with important two-photon absorption properties is bonded to an isomerizable actuator section composed of a stilbenyl-azopyrrole unit. Upon two photon excitation, energy migration from the antenna-localized second singlet excited state to the stilbenyl-azopyrrole section allows for efficient indirect excitation and phototransformation of this actuator. In the experiment, the researchers used Methyltriphenylphosphonium bromide(cas: 1779-49-3Reference of Methyltriphenylphosphonium bromide)
Methyltriphenylphosphonium bromide(cas: 1779-49-3) is a lipophilic molecule with a cation allowing for it to be used to deliver molecules to specific cell components. Also considered an antineoplastic agent.Reference of Methyltriphenylphosphonium bromide
