SnS and SnS2 thin films deposited using a spin-coating technique from intramolecularly coordinated organotin sulfides

Synthesis and applications of organotin(II) sulfide ({2,6-(Me2NCH2)(2)C6H3}Sn)(2)(-S) (1), organotin(II) thiophenolate {2,6-(Me2NCH2)(2)C6H3}Sn(SPh) (2) and organotin(IV) heptasulfide {2,6-(Me2NCH2)(2)C6H3}(2)Sn2S7 (3) as potential single-source precursors (SSPs) for the deposition of SnS or SnS2 thin films using a spin-coating method are reported. Compounds 1, 2 and 3 differ either by tin oxidation state or by Sn:S ratio (Sn:S=2:1 in 1, 1:1 in 2 and 2:7 in 3). It is shown that compound 1 is not a suitable SSP for thin-film fabrication using the spin-coating process because of its incomplete decomposition at annealing temperature. However, compounds 2 and 3 seem to be promising SSPs for spin-coating of amorphous semiconducting thin films of SnS and SnS2, respectively. Copyright (c) 2015 John Wiley & Sons, Ltd.
