| Abstract | A series of 2-(1-benzyl-2-(styryl)-6-methylpyridin-4(1H)-ylidene) fragment containing glassy organic compounds have been synthesized from relevant luminescent 4H-pyran-4-ylidene derivatives and investigated as potential solutionprocessable emitters. Glass transition temperatures of synthesized 1H-pyridine compounds are above 100oC with thermal stabilities higher than 260oC. In the solutions of dichloromethane their absorption bands are in the range from 350 nm to 500 nm with photoluminescence from 500 nm to 650 nm. In a contrary to the 4H-pyran-4-ylidene derivatives, the incorporation of various electron acceptor fragments within the 1H-pyridine fragment containing molecules only slightly influenced absorption and photoluminescence band shifts. Based on these compounds, neat spin-cast films were obtained and investigated as light-emitting mediums which show amplified spontaneous emission (ASE) with λmax in the range from 603 nm to 615 nm with ASE threshold values as low as 46 µJ/cm2. Synthesized 1H-pyridine derivatives show perspective to be applied as solution-processable components for light-amplification studies. |
