Characteristic Analysis of Molecular Photodiode Using Conducting Polymer(PANI) as An Electrode

초록

Molecular photodiode consisted of an electron acceptor(A), a sensitizer(S) and an electron donor(D) is fabricated by mimicking photoinduced electron transfer system in the biological photo thesis. Polyaniline(PANI)-stearic LB of A/S/D stacked on ITO glass. The PANI-SA composite LB films exhibited high electrical conductivity of 10(-1) similar to 10(-2) S/cm upon with HCl or I(2) doping Especially, iodine is found to be the most promising dopant, since it gives a remarkable stability for the molecular photodiode system. The rectifying characteristic and photoswitching function of the proposed molecular photodiode is introduced.
