Fluorescence is an interesting phenomenon emanated in photo-electrical characteirstics of polymers. This feature is used in making highly sensitive polymer sensors. In this study, as part of the introduction given on luminescence and its different types there is a discussion on the production of chemical sensors based on conjugated polymers (CP). This discussion focuses on polymer sensors based on fluorescence polymers, their detection mechanisms, various kinds, pros and cons, different systems of media and future trends. It has been asserted that the chemical sensors based on amplifying fluorescent polymers (AFPs) have suitable semi-conductivity and processability at the same time. Amplifying fluorescent polymers through shifting the excitons in three dimensions and formation of molecular wire show high sensitivity in detection of explosives. The field tests performed by these devices have proved that this technology can be successfully used for high-sensitive detection of explosives, land mines and under-water mines based on nitro-aromatic compounds.
