设计并合成了基于9,9-二烷基芴骨架和邻硝基苯醚的光可切割聚合物，以获得稳定的（n, m）富集的半导体单壁碳纳米管在甲苯中的悬浮液。光照射悬浮液触发了swnt的沉淀，TEM图像显示swnt的紧密堆积表明涂层聚合物的部分去除。
Photocleavable polymers based on 9,9-dialkylfluorene backbone and o-nitrobenzylether were designed and synthesized to obtain stable (n, m) enriched suspensions of semiconducting SWNTs in toluene. Photoirradiation of the suspensions triggered the precipitation of the SWNTs and TEM images indicate close packing of SWNTs pointing at partial removal of the coating polymer.
