文摘
- •
Condensation reaction of 6-bromochromone-3-carboxaldehyde (1) with dimedone afforded BOCTTX.
- •
BOCTTX is thermally stable up to 583 K.
- •
Two direct allowed transitions were observed with band gaps of 2.2 and 3.3 eV.
- •
Sensitivity of BOCTTX/p-Si diode increases with increasing illumination intensity.
- •
Results of BOCTTX/p-Si diode suggest possibility for optoelectronic application.
