AI Article Synopsis
- Two types of compounds were created: linear 1,4-distyrylbenzenes and star-shaped 1,3,5-tristyrylbenzenes, and their properties were analyzed using spectroscopy.
- The study found that extending the backbone or adding dibutylanilines caused a shift to longer wavelengths in their electronic spectra.
- Different arrangements of pyridine units influenced how these compounds responded to various acids and metal ions, successfully distinguishing between several metals like Al, Mn, Fe, Cd, Ag, and Hg.
Article Abstract
Two linear 1,4-distyrylbenzenes and five star-shaped 1,3,5-tristyrylbenzene derivatives (L and L , Y -Y and Y ) were synthesized and spectroscopically characterized. The photophysical properties, optical response to acid and metal ions were investigated. Upon backbone extension of linear distyrylbenzenes or the introduction of dibutylanilines, the electronic spectra are redshifted. Incorporation of electron-deficient pyridyl units does not significantly affect the optical properties. Variation of the number of pyridine rings and substitution pattern tune the fluorescence response to acids and metal ions. The novel arenes discriminate Al , Mn , Fe , Fe , Cd , Ag and Hg .
