Synthetic Approaches to Semiconductive Polymers for Chemical Sensors

Semiconductive polymers have been incorporated in various optoelectronic devices and chemical sensor systems. In order to provide new functions, chemical modification of these polymers is necessary. In the first part, a facile way to modify poly(3-hexylthiophene) (P3HT) will be presented. The method employs a lithium-halogen exchange reaction on brominated P3HT, which generates more than 100 thienyl lithium species in a single polymer chain. The reactive thienyl lithiates can be quenched with a variety of electrophiles, generating derivatized P3HTs. Carbon nanotube-P3HT composites were fabricated for use in chemiresistive sensors. In the second part, functionalization of poly(phenylene ethynylene)s will be introduced. Specifically, through side-chain engineering, this functionalization generates emissive polymer aggregates (emissive excimers) at the air-water interface. The excimers can be transferred to glass substrates, which are responsive to selected volatile organic compounds (VOCs) via fluorescence changes induced by energy migration.
