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.

Therefore, the development of methodologies to obtain Hz synthetically will facilitate an in vitro evaluation of new anti-malarial drugs.
Methods: We present a methodology with good results to obtain Hz from fecal material of blood-sucking insects .
Article Synopsis
- 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.*
