facile exterior alkylation of the polyaromatic framework leads to a moderately fluorescent tube (R=‐OC10H21; ΦF=20 %) in the solid state. The emission intensity of the solid‐state alkyl‐substituted tube is remarkably enhanced upon heating (up to 1.6 times, ΦF=31 %) as well as doping with fluorescent dyes (up to 4.2 times, ΦF=83 %) through efficient energy transfer.
作为关键步骤,通过对二苯蒽衍生物进行立体控制的环三聚反应,以克为单位有效地制备了具有亚纳米级腔的聚芳烃管。聚芳族框架引线的外部容易烷基化以适度荧光管(R = -OC 10 ħ 21 ; Φ ˚F = 20%)在固态下。固态烷基取代的管的发光强度在加热时显着地提高(高达1.6倍,Φ ˚F = 31%),以及用荧光染料掺杂(高达4.2倍,Φ ˚F = 83%)通过高效能量转移。
