This study focuses on synthesis and evaluation of [2.2] paracyclophane-1,9-diene to produce a soluble poly(pphenylenevinylene)
(PPV) derivative homopolymer using ring-opening metathesis polymerization (ROMP).
The resulting homopolymer displayed a narrow polydispersity index (PDI) of 1.22, indicating precise control
over polymerization. The PPV derivative exhibited excellent solubility in various organic solvents. Photophysical
properties, including optical absorption and fluorescence emission spectra, were investigated to evaluate utilization
in optoelectronic devices. Optical band gaps ranged from 2.21 to 2.25 eV for thin films and 2.07 to 2.19 eV
for solutions, while the electrochemical band gap, determined by cyclic voltammetry, was 2.37 eV. These materials
demonstrated promising fluorescence activity in various solvents and thin films, suggesting potential
applications in organic light-emitting diodes (OLEDs) and related optoelectronic devices. |
