| Outline of Final Research Achievements |
Aim of this challenge is creation of world first organic mechanoluminescent (ML) material and sensor. Strategies for achieving been next two; extraction of essential qualities of high performance inorganic ML material, and applying the essence to organic compound. Concretely, main mechanism has been extracted as spatial configuration for mechanoluminescence and electroluminescence in piezoelectric field. First of all, poly vinylidene difluoride (PVDF) was controlled as β phase , in which PVDF shows piezoelectricity, by doping of cray, and successfully generate organic ML field. Second, emissive organic dye have been successfully doped in PVDF without losing piezoelectricity in PVDF and without losing the emissive activity of organic dyes. On the other hand, the intense mechanoluminescence has not achieved. Smart combination of compounds, high efficient field of piezoelectricity, mechanical propagation is promising for final goal and investigation is still on going.
