研究目的
To design and synthesize novel N-heteroacene molecules based on tetraazachrysene units and investigate their photophysical properties, including two-photon absorption capabilities.
研究成果
The study successfully synthesized three novel N-heteroacene molecules with significant photophysical properties, including high fluorescence quantum yields and notable two-photon absorption cross-sections. SDNU-3 exhibited the largest TPA cross-section among heteroacenes, suggesting potential applications in nonlinear optical materials.
研究不足
The TPA cross-sections of the synthesized compounds are relatively small compared to other organic TPA materials, indicating a need for further molecular design to enhance these properties.
