报告内容简介
Nano-carbon imides, especially extended rylene imides are attracting ever-increasing academic attention with aiming at seeking desirable functionality for various optoelectronic devices. The readily derivative nano-carbon skeleton combining easily modifiable imide chains results in a variety of robust materials with intense absorbance and fluorescence, well-tunable energy level, and molecular configuration.
Two kinds of conjugated C3-symmetric perylene dyes, namely triperylene hexaimides (TPH) and selenium-annulated triperylene hexaimides (TPH-Se), will be highlighted. Single-crystal X-ray diffraction studies show that TPH displays an extremely twisted three-bladed propeller configuration and a unique 3D network assembly. TPH and TPH-Se acceptors-based solar cells show high power conversion efficiency >10%, which mainly results from the combined properties of broad and strong absorption ability, appropriate LUMO level, desirable aggregation, high electron mobility and good film morphology with the polymer donor.
Quite recently, the novel nonplanar graphenoid structure, corannurylene pen-tapetalae, has been synthesized via hybridization of five PDI fragments around a corannulene core. Transistor devices demonstrate that, without any π-π stacking, the honeycomb lattice could also facilitate electron transport. The unique example of hybrid graphenoid with a honeycomb crystal lattice expands the scope of complex supramolecular architectures, piquing interest in applications in organic electronics.
