New perylene-substituted organotrialkynyltins C10H20Sp-Sn(C≡CC4H9) 3 (1; Sp = -C4H8-, -C6H12-, -CH=CH-) have been synthesized in two steps from the tricyclohexyltin analogues in fair to high yields (30-90%). Tricyclohexyltin derivatives were prepared in 50% yields either by coupling of 3-perylenyllithium with a (ω-iodoalkyl)tricyclohexyltin or by hydrostannation of 3-ethynylperylene by tricyclohexyltin hydride. Intermolecular π-π contacts between the perylene units were found in the solid-state structure of 3-(4-(tricyclohexylstannyl)butyl)perylene. The presence of a (tricyclohexylstannyl)- or a (trialkynylstannyl)alkyl substituent does not affect the fluorescence emission properties of the perylene core, whereas an ω-(trichlorostannyl)alkyl or a 2-stannylethynyl group does. Molecules 1 are dye precursors for the photosensitization of nanocrystalline tin dioxide materials.
