Silicon Quantum Dot–π Conjugated Molecule Hybrid Polymers |
| 초록 |
The Si QDs capped with π conjugated molecules (1–octene, phenylacetylene, and 1, 4–diethynylbenzene) exhibit red-shift in ultraviolet-visible absorption and photoluminescence spectroscopy. Si QD–π conjugated molecule hybrid polymer was synthesized by cross–coupling reaction. Ultraviolet–visible absorbance, photoluminescence and valence band spectra of the Si QD–π conjugated polymer show absorption band in the range 370–400 nm, emission at 500 nm, and valence band edge at binding enrgy of 4.1 eV which are shifted from those of 4–diethynylstyryl terminated Si QD, indicating strong electronic coupling between Si QDs. The electron transport properties of benzene bridged Si QD dimer was investigated using ATK calculation. The effect of Si QD on electronic structure of capping groups was also examined using Green’s function formalism based on one-particle Schrödinger equation. The Si QD–π conjugated molecule hybrid polymer was tested as anode in Li ion battery. |
