The shoulder peak, which is apparently absent in BMBCP, is ascribed to the ICT transition. On one hand, the congested central part where bulky substituents suspend surround the benzene core leads to largely twisted molecular conformation with shortened conjugation, which might result in a blue-shift tendency; on the other hand, the electron-rich TPA units together with the electron-withdrawing –CN induce the ICT effect in the excited state and give rise to red-shifted emission depending on the solvent polarity. The joint effect between the conjugation and ICT degree definesthe emission of DMCS-TPA. |

| 顯然,BMBCP沒有肩峰,劍鋒是ICT過渡的結(jié)果。一方面,在擁擠的中央部分,大體積的取代基暫停包圍苯芯很大程度上導(dǎo)致分子構(gòu)象的扭曲和耦合縮短,這可能會(huì)導(dǎo)致藍(lán)移傾向; 另一方面,該富含電子的TPA單位連同吸電子-CN誘導(dǎo)處于興奮狀態(tài)的ICT效果,并根據(jù)溶劑的極性引起紅移發(fā)光。耦合和ICT度之間共同作用的程度決定了DMCS-TPA的發(fā)光。 |
