Purpose of the present research project is to fabricate molecular photodiodes whose charge separation mechanism is the same as those in primary processes in photosyntheses. The molecular photodiodes were fabricated by depositing complex langmuir-Blodgett (LB) films which consist of an electron acceptor (A), a sensitizer (S), and an electron donor (D) surfactant derivative, i.e. A/S/D or D/S/A. In these surfactant molecules, viologen, pyrene, and ferrocene moieties act as A, S, and D units, respectively. The photodiode function was also achieved by aligned amphipathic triads which contain three functional units in each molecule (A-S-D).The following terms were studied through the present research project. 1. Fabrication of photodiodes of A/S/D and D/S/A types. 2. Fabrication of photodiodes of AAA/SSSS/DDD type. 3. Determination of photoinduced electron transfer rates in A/S and S/D LB films by ns laser photolysis. 4. Investigation of the energy-gap law for the photoinduced electron transfer. 5. Syntheses of linear and folded types of A-S-D triads molecules. 6. Fabrication of photodiodes with monolayer of the linear or folded types of A-S-D triad molecules. 7. Determination of photoinduced electron transfer rates in A-S or S-D monolayer by ns or ps laser photolysis. 8. Synthesis of A-S-D triads linkes by ritid spacers.

本研究的目的是制作与光合成中的初级过程具有相同电荷分离机制的分子光电二极管。通过沉积由电子受体（A）、敏化剂（S）和电子给体（D）表面活性剂衍生物组成的复合LB膜，即A/S/D或D/S/A，制备了分子光电二极管。在这些表面活性剂分子中，紫精、芘和二茂铁部分分别充当A、S和D单元。光电二极管功能也是通过每个分子中含有三个功能单元（A-S-D）的两亲三元组来实现的。1. A/S/D和D/S/A型光电二极管的制造。2. AAA/SSSS/DDD型光电二极管的制造。3.纳秒激光光解法测定A/S和S/D LB膜中的光致电子转移速率4.光诱导电子转移能隙定律的研究。5.线性和折叠型A-S-D三联体分子的合成。6.具有线性或折叠型A-S-D三元组分子的单层光电二极管的制造。7.用ns或ps激光光解法测定A-S或S-D单分子膜中的光诱导电子转移速率。8.通过Ritid间隔基合成A-S-D三联体连接物。
