We present an experimental and theoretical investigation of the linear and nonlinear optical properties of a series of acceptor-pi-acceptor symmetrical anionic polymethine dyes with diethylamino-coumarin-dioxaborine terminal groups and different conjugation lengths. Two-photon absorption (2PA) cross sections (delta(2PA)) are enhanced with an increase of pi-conjugation length in the investigated...
Photostable donor–acceptor–donor fluorophores, which have a central quinoxaline acceptor nucleus, been used in LSCs, obtaining outstanding results for modern building-integrated photovoltaics (BIPV).
Transient absorption and time-resolved fluorescence measurements in a wide temperature range are used to investigate the mechanism of charge carrier generation efficient organic solar cells based on PM6:Y6 donor–acceptor blend. The mechanisms differ significantly under excitation donor or acceptor. investigations reveal temperature-dependent interplay between formation interfacial transfer (CT)...
We present herein a new and efficient four-component synthesis of isoxazol-5(2H)-ones involving ring closing/Knoevenagel condensation/Michael addition sequential reactions.
