A π-conjugated polymer (PBQT) containing bis-(2-ethylhexyloxy)-benzo [1,2-b'] bithiophene (BDT) units alternated with a quinoline-vinylene trimer was obtained by the Stille reaction. The chemical structure of the polymer was verified by nuclear magnetic resonance (H NMR), Fourier transform infrared (FT-IR), and mass spectroscopy (MALDI-TOF). The intrinsic photophysical properties of the solution were evaluated by absorption and (static and dynamic) fluorescence.

- The study focuses on the synthesis of two oligophenyleneimine pentamers, DAFCHO and FDACHO, which contain terminal aldehydes, using mechanochemistry methods and various diamines.* -
- The compounds were characterized using spectroscopy techniques (¹H and C-NMR, FT-IR, mass spectrometry) and displayed interesting photochromic properties in chloroform when exposed to sunlight, with notable energy band gap values measured.* -
- Electrochemical studies revealed their potential as organic semiconductors, with HOMO and LUMO values indicating favorable electronic properties, and findings were further supported by Density Functional Theory (DFT) calculations.*
