New fluorescent dual-emission dyes

Color tunable fluorescent molecules in liquid and solid state for white and colour applications

TECHNOLOGY

• Dual-emission fluorescent molecule family
• Dual emission with one molecule only
• Fluorescence up to 54% for color and 30% for white
• Color tunable with electrodonating or attracting substituents

APPLICATIONS

• Solid-state lightning
• Optoelectronics
• Analytical chemistry or biochemistry
• Ratiometric detector
• Dye or pigment for colouring or light brightening

INNOVATION ADVANTAGES

• Solid and liquid state fluorescence (on the contrary of most π-conjugated dyes)
• Few steps only synthesis
• Successful integration in polymer films and matrix (Higher quantum yield than in fluid solution)

DEVELOPMENT STATUS

• Synthesis and fluorescence testing of 11 compounds
• Improvement of quantum yield , lifetime and color
