The present research project was organized to achieve the co-operative hybridization of electron-transfer processes by co-operative unions between researchers of various fields such as organic reaction and synthesis, electrochemistry catalysis, and biological functions. The researchers relating electron-transfer processes exchanged their concept with researchers of different fields. One meeting was the 18th EOC Symposium (Nagoya, June, 1995) and the other was the open symposium of present co-operative research (A) (Nagoya, November, 1995).The present research is related to three projects : (1) developments of hybridized electron-transfer systems by surface modifications. (2) molecule transformations by catalyst-electrode composite systems, and (3) molecular transformations by combinations of biological and electrode reactions. These projects are related to electron transfer processes and their co-operative hybridization could lead to selective transformations and function amplifications. For example, highly selective transformations of substrates were achieved by electron transfer mediators such as metal complexes and aromatic compounds. Composite electrodes containing enzymes have been shown to be a good selective sensor. Controlles of electron transfer processes have been achieved considerably and a basic concept for co-operative hybridization could be developed.
