Results and discussion
DSC thermograms of styrylcarbazole fluorophores from 2nd heating cycle at 10 °C/min
Results and discussion
Normalized absorption (dotted line) and fluorescence spectra (solid line)
of the styrylcarbazole fluorophores in THF solution.
Cz-SiPh : 344 nm absorption
411 nm : Blue emission
Cz-NPh : 351 nm absorption
447 nm : Blue emission
Cz-Ph3 : 391 nm absorption
510 nm : green emission
Results and discussion
The result was measured in a three electrode compartment cell with a Pt wire counter electrode and a Ag/AgCl (0.1 M) reference electrode at a scan rate of 50 mV/s. The electrolyte was TBAP (tetrabutylammonium-perchlorat) (0.1 M)
in dichloromethane solvent
potentials for oxidation
CzNPh : 0.85V
CzPh3 : 0.86V
CzSiPh : 1.05V
