英文摘要	Harvesting high-purity semiconducting single-walled carbon nanotubes (s-SWCNTs) with removable dispersants remains a challenge. In this work, we demonstrate that small heteroacene derivatives may serve as promising selective dispersants for sorting s-SWCNTs. A rich N "doped" and thiophene-substituted hexaazapentacene molecule, denoted as 4HP, was found to be more favorable for high-purity s-SWCNTs with large diameters. Importantly, 4HP is photodegradable under 365 nm or blue light, which enables a simple deposition approach for the formation of clean s-SWCNT networks. The as-fabricated thin film transistors show excellent performance with a charge-mobility of 30-80 cm(2) V-1 s(-1) and an on-off ratio of 10(4)-10(6).; National Natural Science Foundation of China [61274130, 21373262]; Natural Science Foundation of Shandong Province, China [ZR2014BQ015]; MOE [RG 16/12, RG RG133/14, ARC 20/12, ARC 2/13]; CREATE program (Nanomaterials for Energy and Water Management) from NRF, Singapore; SCI(E); PubMed; ARTICLE; sqiu2010@sinano.ac.cn; lihaibei@sdu.edu.cn; qwli2007@sinano.ac.cn; 49; 7683-7686; 52
