The investigation of sky-blue emitting anthracene-carbazole derivatives: Synthesis, photophysics and OLED applications

Blue organic light-emitting diodes with hybridized local and charge-transfer excited state realizing high external quantum efficiency

“…The ratio of the delayed component decreased from 3 V to 10 V because of the quenching of dark triplet excitons and the amplified delayed component obtained from the plot of log EL intensity and log time [slope: −0.21 (initial time); −1.46 (log time)] ( Fig. 3 ); 58 however, the slope should be −2 instead of −1.46 for the TTA mechanism. Therefore, the TTA configuration is insignificant in the EL process.…”

Exploring the potential of anthracene derivatives as fluorescence emitters for biomedical applications

“…The lifetime decay measurements (from 400 ps to 1 s) were performed with a high-energy pulsed Nd:YAG laser that is wellintegrated with a spectrograph and the emission is monitored with a very sensitive gated iCCD camera system previously presented as a proficient technique for time-resolved spectroscopy. [29][30][31] The laser has a wavelength of 355 nm (SL312, EKSPLA), and a pulse duration of about 150 ps. During temperature-dependent fluorescence measurements, the materials were taken under vacuum (B10 À3 mbar) and placed in a cryostat system for characterisation.…”

Unveiling All‐Optical Switching Phenomenon in Anthracene Derivatives: A Comprehensive Study on Optical and Nonlinear Optical Multifunctionality

“…[30][31][32] It is noteworthy that small anthracene-like molecules -especially the asymmetrical ones [33,34] have proven to be attractive building block for the blue OLEDs due to their outstanding electroluminescence properties, and high photothermal stability. [35] Furthermore, anthracene derivatives are used in the synthesis of the nanostructured thin films for semiconductors in optoelectronics. [36][37][38] Various other forms of anthracene have become objects of extended research, including photoluminescent nanorods, [39] organogels, [40,41] and polymers, [42,43] accordingly.…”
