Book Description

A description of how semiconducting fluorescent polymers function as chemosensors for a variety of chemical vapors is presented. Amplification is achieved by transport of optically induced excitations throughout a polymer film. Careful and thoughtful design of polymer chemical structures is crucial to achieving high sensitivity towards nitroaromatic explosives such as trinitrotoluene (TNT) and dinitrotoluene (DNT). These semiconductive materials have been incorporated into functional sensory devices used for ultratrace explosive detection in the search for hidden landmines. Research efforts in our group have been aimed improving the sensitivity, selectivity, and versatility of conjugated polymer sensors through rational molecularly design.

Book Description

In this dissertation, we established a new approach assisted by computational chemistry to design fluorescent sensors. The approach is applicable to predict the behavior of a fluorophore-bridge-receptor sensor based on photoinduced electron transfer (PET). Our first designed rhodamine based pH sensor exhibits strong fluorescence under acidic conditions and very weak fluorescence under basic conditions, just as the computations predicted.

Book Description

This report describes our effort in the past three years on synthesis and characterization of novel photorefractive polymer system. Two major systems were developed, one of which combined the ionic transition metal complexes and a conjugated polymer backbone bearing NLO chromophores to manifest large photorefractive effect. Another is a molecular material containing oligothiophene and a nonlinear optical (NLO) chromophore. A large net optical gain (>200/cm) at a zero electric field was observed in the metal containing system. In the molecular system, a net optical gain of 83/cm and a diffraction efficiency of nearly 40% were obtained in a film made from this molecule under an applied field of 706 kv/cm. A fast response time of for the grating formation, 42 ms under 616 kv/cm, was observed.
