The thermal stability of organic materials is critical for their applications as luminescent emitters because thermal stability governs the stability and lifetime of devices. If a device is heated above theTg of its organic material components, irreversible failure can occur. Hence, a relatively high Tg is essential for emissive materials used for optoelectronic applications. Thermal properties were investigated by differential scanning calorimetry (DSC) and thermal gravimetric analysis (TGA). The Tg values of1B-TPA, 2B-TPAand3B-TPAwere 137.9, 196.7 and 214.3 C, respectively, which were much higher than those of the two reported typical AIE-active compounds, 1-methyl-1,2,3,4,5-pentaphenylsilole (MPPS, 54 C) and 1,1,2,3,4,5-hex-aphenylsilole (HPS, 65 C). 11 The highTg is attributed to the effect of the bulky carbazolyl groups. To the best of our knowledge, theTg of3B-TPAis currently the highest reported for organic luminescent materials with AIE properties. The highestTgfound for AIE compounds was at 204 C, which was reported by Tang. 12 As expected,Tgvalues increased with a rise in the number of dicarbazolyl triphenylethylene substituents. Tri-substituted3B-TPApossessed the highest Tg of up to 214.3 C. |
