  the standard reduction potential of the dye. The feasibility of employing a colloidal semiconductor system in the operation of a photogalvanic cell is demonstrated. A photogalvanic power conversion efficiency of 0.002% was achieved with thionine and colloidal TiO2 upon bandgap excitation.

  噻嗪和恶嗪染料已通过带隙激发在胶态TiO 2悬浮液中进行了光电化学还原。染料的单电子还原导致半还原的自由基离子的产生，量子产率高达0.1，进一步歧化产生了稳定的无色染料。发现界面电子转移过程的效率取决于染料的标准还原电位。证明了在光原电池的操作中采用胶体半导体系统的可行性。在带隙激发下，用硫氨酸和胶体TiO 2实现了0.002％的光电电流转换效率。TiO 2的用途 还讨论了将胶体用作在电极表面上沉积光活性或电活性物质的载体。
• Immobilization of components in polymer membrane-based calcium-selective bulk optodes

  A large variety of optical sensors based on thin plasticized PVC membranes have been realized in the past. The organic membrane (bulk optode) contains the analyte recognition molecule such as a selective neutral ionophore, a H+-selective chromolonophore, and lipophilic anionic sites. In order to improve the lifetime of analytically relevant sensing layers, their active components are covalently immobilized to the polymeric matrix. Different Ca2+-selective bulk optodes with mobile or fixed chromolonophores and anionic sites are characterized and discussed with respect to sensor behavior such as dynamic range, repeatability, response time, selectivity, and lifetime. In general, the response time increases upon immobilization of components owing to limited diffusion within the membrane phase, whereas the lifetime is enhanced drastically by a hindered loss of membrane components Into the sample.
