Abstract

The hybridization of functional polyacetylenes with lead bromide perovskite was investigated. It was observed that the perovskite induces the nonmesogenic polyactylene chains to align like liquid crystals within the inorganic layers. It was shown that photoenergy is efficiently transferred from the perovskite framework to the polyacetylene chains, and the chain interactions are suppressed by the segregation of the polymer chains in separate perovskite layers. It was found that the energy transfer and chain separation both help enhance the light emission efficiency of the hybrids.
