Fluorinated Materials for Air-stable and Moisture-resistant Flexible Optoelectronics.

摘要

This project provides a new materials solution for air-stable moisture-resistant flexible optoelectronics for smart battlewear. Major scientific contributions of this project are: (1) developed new synthetic methods for preparing perfluoroalkylated aromatic compounds that are key to the organic semiconductor industrials; (2) discovered the threshold of aromatic perfluoroalkylation that can make air-stable n-type organic semiconductor materials; (3) revealed a fundamental understanding that leads to controllably formation of solid state materials with desired structure, important for improving charge transport in organic semiconductor devices; (4) elucidate the structure-function relationship of n-type organic semiconductor materials through both experimental and computational approaches; and (5) discovered a new experimental approach to lead to highly photochemically stable organic semiconductor materials which is key to the practical application of flexible organic solar cells. The success of this project brought foremost benefits to national defense applications including: (1) the optoelectronic devices (OSCs and OLEDs) build with these robust materials will be able to operate under extreme environmental condition; (2) providing new materials for power generation (flexible solar cells) and storage in the battle field for individual warrior where other form of power supply and storage is not available.
