Two-dimensional materials, such as graphene and monolayer transition metal dichalcogenides, allow the fabrication of multilayer structures without lattice matching restriction. A central issue in developing such artificial materials is to understand and control the interlayer electron transfer process, which plays a key role in harnessing their emergent properties. Recent photoluminescence and ...

N-type pyrazine-based 1,4- and 1,5-disubstituted 1,2,3-triazole derivatives, showing unique aggregation-enhanced emission characteristics, were facilely prepared via Cu- and Ru-catalysed azide-alkyne cycloadditions, respectively. Thanks to their electron-deficient properties, they could readily form red-emissive charge transfer complexes with electron-donating triphenylamine in the aggregate an...

Multi-step electron transfer is increasingly recognized as a means for moving charge in biological systems over long distances rapidly. Many postulated multi-step mechanisms rely on the formation of organic radicals (amino-acid radicals, nucleobase radicals) as intermediate electron or “hole” carriers. In this thesis, the multi-step mechanism for electron transfer in both proteins and DNA is in...
