Meti, Puttavva published the artcileSynthesis, characterization and optoelectronic properties of pyrrolopyrazine based Y-shaped color-tunable dipolar molecules, Category: pyrazines, the main research area is color tunable pyrrolopyrazine preparation thermal optoelectronic fluorescence.
A regioselective approach for the synthesis of functionalized dipolar Y-shaped chromophores is demonstrated. A series of dipolar pyrrolopyrazine based mols. were prepared in a straightforward manner. The key step in the preparation of the chromophores involves two-fold Sonogashira coupling reaction between the pyrrolopyrazine core and acetylene derivatives Different electron-donors, including, NH2, NMe2, OMe and CF3, CN acceptors were incorporated into the chromophores. By adjusting the substituents at 2, 3, and 6-position of the pyrrolopyrazine, dipolar tunable mols. with wide emission band are synthesized. The optical, thermal, and electrochem. properties of the materials are analyzed and the results are supported with the DFT calculations The preliminary studies of these engineered Y-shaped mols. indicate their potential as new building blocks in the fields of optoelectronic devices.
