Development of stimulus-responsive polydiacetylene systems for molecular colorimetric detection
… to achieve this goal, I have rationally designed polydiacetylene systems that possess unique optical properties such as color changing in the presence of external stimulus. These advanced polydiacetylene systems are conjugated with functional groups having specific targeting ability toward …

Development and thermal characterization of polydiacetylene (PDA) nanofiber composites for smart wound dressing applications
Conventional methods of identification of microbiological pathogens infection in wound have many challenges such as the need for specialized instruments and trained personnel, and the long detection time. There is a critical need for an innovative method that is simple, accurate, sensitive, …

Inkjet printing multifunctional chromatic sensors and chromism study
The thermochromism and chemochromism of polydiacetylene (PDAs) and PDA/ZnO nano composites have been systematically studied by attentuated total reflection (ATR)- Fourier transform infrared (FTIR), temperature-dependent Raman, colorimetric (using optical densitometry) and differential scanning …

USING CONJUGATED POLYMERS AS BIOLOGICAL SENSOR BASED ON FLUORESCENCE RESONANCE ENERGY TRANSFER
… transfer (FRET) between fluorophore (donor) and polydiacetylene (PDA, acceptor) for selective detection of biomolecules in solution. The work described in this dissertation is divided into three sections. In the first section, we report here two novel systems where the rate of energy transfer is …

The optical cubic susceptibility dispersion of some transparent thin films.
… the near resonant cubic susceptibility of the polydiacetylene, poly(4-BCMU). In that case tunable Third-Harmonic-Generation and Two-Photon-Absorption measurements both agreed with the result of a Near-Infrared-Three-Wave-Mixing measurement. In the case of β-carotene and polythiophenes the four …

Coherent Control of Molecular Dynamics with Shaped Femtosecond Pulses
… is the control of the ground state dynamics in polydiacetylene. In a Raman step with a shaped Stokes pulse, the population of the backbone vibrations of polydiacetylene in its ground state could be controlled. A consecutive probe pulse in a CARS (coherent anti-Stokes Raman scattering) …

Applications for nanomaterials in critical technologies
… and thermal properties for successful CMP. A new polydiacetylene thermosetting polymer (DEB-TEB), which displays a low dielectric constant (low-k) of 2.7, was recently developed. This novel material appears to offer the only avenue for designing an ultra low k dielectric (1.85k), which can still …
