9-顺视黄醛可以经形成去质子化的席夫碱来模拟天然的细菌视紫红质,但是其光电流和稳定性都较低,通过在其中掺杂超细金颗粒可以显著提高其光电性能。利用石英晶体微平衡、循环伏安法和吸收光谱等分析方法初步研究了纳米金颗粒作用的机理,认为金颗粒与9-顺视黄醛质子化席夫碱LB膜结合可形成新的更为稳定的络合物,影响了席夫碱的氧化还原电位,并且加速了跨膜电子的传输,从而明显地改善了光电性能。为在人工视网膜及分子电子器件方面的应用打下了基础。
9-cis-retinal can mimic the natural bacteriorhodopsin by forming a deprotonated Schiff base, but its photocurrent and stability are both low, by which it is possible to significantly increase its optoelectronics by doping ultrafine gold particles performance. The mechanism of action of gold nanoparticles was preliminarily studied by means of quartz crystal micro-balance, cyclic voltammetry and absorption spectroscopy. It is believed that the combination of gold particles and 9-cis-retinal protonated Schiff base LB film can form new more The stable complex, which affects the redox potential of the Schiff base, accelerates the transport of transmembrane electrons and thus significantly improves the optoelectronic properties. Laid the foundation for the application of artificial retina and molecular electronic devices.
