“…The alkyl chain has minimal effect on the Δ E g value. Consequently, the HOMO‐LUMO transition, which is the dominant contributing configuration to the S 1 state in MR1A ‐ MR1C is traced back to the mixing of π‐π* with the ICT feature, which is consistent with our analysis of the low‐energy absorption shoulders in the UV‐vis absorption spectra [29] . When an electron‐donating substituent (−CH 3 ) is introduced, the HOMO energy level increases, which could result in a redshift in the absorption [30–31] .…”

“…ChemistrySelect with our analysis of the low-energy absorption shoulders in the UV-vis absorption spectra. [29] When an electron-donating substituent (À CH 3 ) is introduced, the HOMO energy level increases, which could result in a redshift in the absorption. [30][31] This is similar to that observed in UV-vis absorption spectroscopy (Section 2.2).…”

“…It is noteworthy that aromatic dendrimers bearing a 2,4,6-triphenyl-1,3,5-triazine skeleton as the core molecule feature improved thermal stability and beneficial photophysical properties associated with improved electron-transfer processes. 4 6 Thus, many examples of 2,4,6-triphenyl-1,3,5-triazine-based aromatic dendrimers were reported in the literature, with fluorene, 4 , 7 9 carbazole, 10 12 pyrene, 13 phenoxazine, 14 bithiophene, 15 oxadiazole, 16 or long-chain alkoxyl groups 17 acting as a dendron motif. The above-mentioned molecules were found to exhibit beneficial light-emission properties, e.g., toward the construction of organic-light emitting diodes 4 , 11 − 15 or liquid crystalline materials.…”

“…Aromatic dendrimers represent an important class of highly ordered and monodisperse molecules, the properties and functions of which can be tuned by the selection of different cores and dendrons. , Over the past 20 years, low-generation aromatic dendrimers bearing 1,2,3-triazine skeletons have been intensively explored, because of their encouraging properties and functions as well as many prospective applications. It is noteworthy that aromatic dendrimers bearing a 2,4,6-triphenyl-1,3,5-triazine skeleton as the core molecule feature improved thermal stability and beneficial photophysical properties associated with improved electron-transfer processes. Thus, many examples of 2,4,6-triphenyl-1,3,5-triazine-based aromatic dendrimers were reported in the literature, with fluorene, , carbazole, pyrene, phenoxazine, bithiophene, oxadiazole, or long-chain alkoxyl groups acting as a dendron motif.

“…Other studied star-shaped structures of particular interest are 1,3,5-triazines, as they possess desired optoelectronic and photovoltaic properties [ 8 , 9 , 10 ]. Moreover, a combination of 1,3,5-triazines and carbazole moieties in single molecules significantly improves their performance [ 11 , 12 , 13 , 14 , 15 ]. Different aspects of carbazole properties and their use in light-emitting applications have recently been reviewed [ 16 ].…”
