• First report of poly(phenylene vinylene) intercalation in layered MnPS3.
• Compares systems based on high- and low-temperature synthesized MnPS3.
• Structural and spectroscopic studies of the intercalates.
• The hybrid organic-inorganic materials show stable photoluminescence.
• Electronic conductivity is increased after the intercalation reaction.
The preparation of luminescent semiconducting nanocomposites of crystalline and amorphous manganese phosphorus trisulfide (MnPS3), containing intercalated poly(phenylene vinylene) [PPV] is reported. The materials were characterized by thermogravimetric analysis, infrared and Raman spectroscopy and X-ray diffractometry. Scanning electron microscopy was used to monitor the crystallinity and morphology of the host materials.An average increase of 5.05 Å in the interlayer distance of MnPS3 was observed by XRD, as a result of the intercalation of PPV. The resulting composite materials presented more stable photoluminescent properties than unintercalated PPV, and with slightly blue-shifted emission; they exhibited significantly higher electronic conductivities than MnPS3 or the polymer alone. The effects of the intercalation host on the optical and electronic properties of the PPV guest are discussed.
