Thionated naphthalene diimides: tuneable chromophores for applications in photoactive dyads (2017)
Journal Article
Pearce, N., Davies, E. S., Horvath, R., Pfeiffer, C. R., Sun, X., Lewis, W., …Champness, N. R. (2018). Thionated naphthalene diimides: tuneable chromophores for applications in photoactive dyads. Physical Chemistry Chemical Physics, 20(2), https://doi.org/10.1039/c7cp06952a

Varying the degree of thionation of a series of naphthalene diimide (NDI) and naphthalic imides (NI) phenothiazine dyad systems afford a systematic approach for tuning of the system’s donor-acceptor energy gap. Each dyad was compared to model NDI/NI... Read More about Thionated naphthalene diimides: tuneable chromophores for applications in photoactive dyads.
