Panchromatic luminescent D–π–A benzothiazoles with different π-bridging modulation: design, synthesis and application in WLED devices

Abstract

White light-emitting diodes (WLEDs) are gradually replacing traditional lighting devices and are becoming the mainstream photosource, having advantages of low energy consumption and high efficiency. However, higher brightness and color...

Solid-Phase Synthesis of 2-Benzothiazolyl and 2-(Aminophenyl)benzothiazolyl Amino Acids and Peptides

“…High Performance Liquid Chromatography (HPLC) analysis was performed on a Waters 2695 multisolvent delivery system (Milford, MA, USA), combined with a Waters 991 photodiode array detector. The following columns were used: (A) Lichrosphere RP-8, 5 μm, 125-4 mm; (B) Zorbax SB-C18, 3.5 μm, 30…”

“…2-phenylbenzothiazoles have also shown interesting metal-involved noncovalent interactions [ 27 , 28 , 29 , 30 ] with broad applications in materials science, while in the diagnostic area, many metal-radiolabeled 2-phenylbenzothiazole derivatives are continuing to be explored as amyloid imaging agents [ 23 , 31 , 32 , 33 ]. Non-metal-based positron emission tomography (PET) imaging of Aβ plaques is also possible through the use of radiolabeled benzothiazoles such as the 18 F-labeled derivative of 2-(4-aminophenyl)benzothiazole [ 18 F] Flutemetamol, which gained approval in 2013 for clinical use [ 34 , 35 ].…”

“…The condensation of 2-(4-aminophenyl)benzothiazole with amino acids has been achieved by its reaction with 1-hydroxybenzotriazole activated amino acids [25]. Besides the limitations of the ap plied chemistries during 2-(4-aminophenyl)benzothiazole synthesis (high temperatures complex product mixtures, substrate dependence) and the conjugation of 2-(4-aminophe nyl)benzothiazole with 1-hydroxybenzotriazolyl amino acids (low reactivity, repeated 2-phenylbenzothiazoles have also shown interesting metal-involved noncovalent interactions [27][28][29][30] with broad applications in materials science, while in the diagnostic area, many metal-radiolabeled 2-phenylbenzothiazole derivatives are continuing to be explored as amyloid imaging agents [23, [31][32][33]. Non-metal-based positron emission tomography (PET) imaging of Aβ plaques is also possible through the use of radiolabeled benzothiazoles such as the 18 F-labeled derivative of 2-(4-aminophenyl)benzothiazole [ 18 F] Flutemetamol, which gained approval in 2013 for clinical use [34,35].…”

Modulating multi-color room temperature phosphorescence emission for carbon dot composites with ultralong lifetime

“…Controlling emission color is a key topic for luminescent materials because of their various applications such as multi-color imaging, 1,2 sensing, 3 optoelectronics, 4 and information encryption. 5,6 In the past decade, exploring fluorophores that combine multi-color 7–9 and quantum yield (QY) 10,11 was of extensive interest. Compared with conventional fluorescent materials that reemit almost immediately, RTP materials have a unique advantage that their detection time can be extended above 10 8 orders.…”
