- Atom-efficient synthesis of 2,4,6-trisubstituted 1,3,5-triazinesviaFe-catalyzed cyclization of aldehydes with NH4I as the sole nitrogen source
-
An atom-efficient, straightforward method for the synthesis of 2,4,6-triaryl-1,3,5-triazinesviairon-catalyzed cyclization of aldehydes with NH4I as the sole nitrogen source is demonstrated. This strategy works smoothly under air atmosphere, and affords symmetrical 2,4,6-trisubstituted and unsymmetrical 1,3,5-triazines with yields from 18% to 72%. Compared to other methods, the present protocol provides a straightforward and atom-efficient approach to 2,4,6-trisubstituted 1,3,5-triazines using an inexpensive, easily available ammonium salt as the sole nitrogen source. Research into the preliminary mechanism indicates thatN-benzylidenebenzimidamides are involved in this cyclization reaction.

- Engineering the Interconnecting Position of Star-Shaped Donor–π–Acceptor Molecules Based on Triazine, Spirofluorene, and Triphenylamine Moieties for Color Tuning from Deep Blue to Green
-
Pi-conjugated organic molecules featuring the donor–bridge–acceptor (D–π–A) structure have been widely used in semiconducting materials owing to their rigid structure, good thermal stability, excellent charge transfer, and high emission efficiency. To investigate the effect of the D–π–A molecular structure on the photophysical properties, in this contribution, three star-shaped D–π–A isomers based on the 2,4,6-triphenyl-1,3,5-triazine, spirofluorene, and triphenylamine moieties, that is, p-TFTPA, mp-TFTPA, and m-TFTPA, were synthesized by elaborately engineering the interconnecting position in the building-block units. The optophysical properties of these compounds were systematically explored by experiments and theory calculations. Definitively, changing the interconnecting position in these molecules played a significant role in the degree of π conjugation, which resulted in tunable emission colors from deep blue to green. Moreover, these isomers were employed as emissive dopants in organic light-emitting diodes. The highest external quantum efficiency of 2.3 % and current efficiency of 6.2 cd A?1 were achieved by using the p-TFTPA based device. This research demonstrates a feasible way to realize blue emitters by engineering D–π–A conjugation.

- Thermally activated delayed fluorescence of N-phenylcarbazole and triphenylamine functionalised tris(aryl)triazines
-
N-phenyl carbazole and triphenylamine functionalized tris(aryl)triazines, as well as the corresponding mononers, have been synthesized by Suzuki cross-coupling reactions. The electronic, photophysical and electrochemical properties of these materials can be effectively tuned by manipulation of the constitution of acceptor and donor units. N-phenyl carbazole and triphenylamine functionalized 2,4,6-trisphenyl-1,3,5-triazines exhibit small energy gaps between the singlet and triplet (0.24 eV and 0.18 eV), and offer potential for application as thermally activated delayed fluorescence materials. The results are supported by time-dependent density functional theory calculations, delayed and time-resolved fluorescence data.
