Abstract
A highly sensitive fluorescent sensor for trace amounts of water based on photo-induced electron transfer (PET) has been developed and the PET-type fluorescent sensor-doped polymer films for moisture and water droplets were prepared.
Highlights
PaperThe optical sensing properties of these fluorescent sensors for the detection and quantification of water content were investigated from the viewpoints of the relationship between ICT, ESIPT, PET, or solvatochromic characteristics and the intermolecular interaction of the sensors with water molecules
We have achieved the preparation of various types of polymer films (polystyrene (PS), poly(4-vinylphenol) (PVP), polyvinyl alcohol (PVA), and polyethylene glycol (PEG)) doped with SM-1, and investigated the optical sensing properties of the SM-1-doped polymer films for water
In order to develop fluorescent polymeric materials for the visualization and detection of water, we have achieved the preparation of various types of polymer films (PS, PVP, PVA, and PEG) doped with SM-1, and investigated the optical sensing properties of the SM-1-doped polymer films for water
