title: A 'chemically-gated' photoresponsive compound as a visible detector for organophosphorus nerve agents.
abstract: We describe a versatile and convenient visible detection method for organophosphorus compounds based on a colorless 'pro-photoresponsive' organic molecule that undergoes photochemical ring-closing to produce a colored isomer only after it reacts with vapors of the phosphorylating agent.
