AI Technical Summary
Technical Problem
Conventional road markings are not sufficiently visible at night or in low light conditions, are affected by adverse weather, and require energy-intensive lighting systems, leading to safety and maintenance challenges.
Method used
A fluorescent paint is developed using 9,10-di[(4-triphenylsilyl)phenyl]ethynyl-anthracene dye in a resin mixture, which absorbs sunlight or car headlights to emit bright green light, enhancing visibility and durability under various conditions.
Benefits of technology
The paint provides clear road markings that reduce the need for external lighting, increase safety by improving visibility, and lower maintenance costs, while being cost-effective and environmentally friendly.

Abstract
Present invention relates to a method for producing green fluorescent paint for use as a lighting for energy-efficient highway lane and park markings, characterized as comprising following production steps; adding 9,10-dibromoanthracene, CuI, Pd catalyst, diisopropylamine and toluene in a reaction flask under nitrogen atmosphere and stirring them on a magnetic stirrer, adding tetraphenylsilanacetylenyl to the mixture and performing reflux distillation by increasing the reaction temperature, after 24 hours bringing the temperature to room temperature, obtaining pure product from the mixture brought to room temperature using column chromatography, taking 0-1% by mass of the product and mixing it in resin and an aromatic solvent for 6-24 hours.
