Applications

2-Thionaphthol was used in the preparation of cholesterol monolayer and multilayer Langmuir- Blodgett (LB) films. The magnetic resonance shift for a self-assembled monolayer of 2-naphthalenethiol was studied that suggested considerable promise in flexible and transparent photonic devices for biological and chemical sensing.

Notes

Store in cool place. Keep container tightly closed in a dry and well-ventilated place. Air sensitive. Incompatible with strong oxidizing agents.
