Mason, Christopher R. and Li, Yang and O'Brien, Paul and Findlay, Neil J. and Skabara, Peter (2011) Sexithiophenes as efficient luminescence quenchers of quantum dots. Beilstein Journal of Organic Chemistry, 7. pp. 1722-1731. ISSN 1860-5397 (https://doi.org/10.3762/bjoc.7.202)

Abstract

Sexithiophenes 1a and 1b, in which a 4-(dimethylamino) phenyl unit is incorporated as an end-capping group, were synthesised and characterised by cyclic voltammetry, absorption spectroscopy and UV-vis spectroelectrochemistry. Additionally, their ability to function as effective luminescence quenchers for quantum dot emission was studied by photoluminescence spectroscopy and compared with the performance of alkyl end-capped sexithiophenes 2a and 2b.
