Outline of Final Research Achievements

New efficient methods for the synthesis of phosphole/thiophene-containing π-conjugated molecules were established, and their structure-property relationships were unveiled using various spectroscopic techniques and X-ray diffraction analyses. Some derivatives with high visible-light absorbing ability were used for organic solar cells. In addition, a new class of highly fluorescent derivatives was constructed. All the results show that the newly constructed phosphole/thiophene-containing hybrid derivatives would be promising candidates as organic materials.
