Dissociation exists in s-triazine based donor-accepter organic systems by photo-induced electron transfer

In the organic donor-acceptor system, the dissociation of the chloride anion in the s-triazine group as the acceptor was first investigated under irradiation. Introducing the electron-deficient chromophore as acceptor 2 to the donor-acceptor module allows the photo-induced electron transfer from the...

Description
Summary:In the organic donor-acceptor system, the dissociation of the chloride anion in the s-triazine group as the acceptor was first investigated under irradiation. Introducing the electron-deficient chromophore as acceptor 2 to the donor-acceptor module allows the photo-induced electron transfer from the s-triazine module, making the dissociation less in the donor-acceptor1-acceptor2 architecture, which has been proven to be a good strategy to increase light-stability. [Display omitted] •Introducing the electron-deficient chromophore as acceptor 2 to donor-acceptor module increases its light-stability.•Transferring the photo-induced electron to acceptor 2.•Therefore by preventing the dissociation of chloride anion in the donor-acceptor systems.
