Effect of Solvent on the Morphology and Microstructure of Light Emitting Organogels

Summary: Self assembly of oligo(phenylene vinylene) based gelator is studied in three different solvents namely, trans-decahydronaphthalene (trans-decalin), benzene and benzyl alcohol. The morphology as well as the thermal properties are different for benzyl alcohol gel as compared to those gels in trans-decalin or benzene. X-ray diffraction studies indicate that in case of benzyl alcohol gel, the molecular organization is highly ordered with respect to the fibrils grown in other two solvents.
