AI Thread Summary
Fluorescent paints that are invisible under normal light but visible under UV light contain specific fluorescent chromophores that absorb UV radiation and emit visible light. The key to their chemical structure lies in the functional groups used during synthesis, with many fluorescent dyes incorporating aromatic compounds, particularly benzene rings, which are known to facilitate fluorescence. These compounds undergo electronic transitions when exposed to UV light, resulting in the emission of longer-wavelength light. The discussion emphasizes the importance of understanding the chemical structure of these chromophores for anyone interested in creating or using invisible paints. Additionally, there is a noted difficulty in finding such paints in local stores, as many available options are visible under both normal and UV light.

What is general chemical structure of fluorescent paints (one’s that are invisible except when radiated with UV light).

I’m especially interested in this because I would like to maybe paint something on walls of my room invisibly, but seen under UV lamp (cool, a ?:)). :biggrin:

But I can't find (except on the net) that kind of colors in my stores (there are ones that are both visible under “normal” light and UV light, but I don’t want them).

+ I’m interested in chemistry, so I would like to know it’s structure.
 
Chemistry news on Phys.org
First of all, let me discuss the term "fluorescent" in terms of physics and chemistry:

If an ultraviolet (or X-rays, cathode rays, etc) radiation is absorbed and emitted as longer-wavelength-rays, this is called fluorescence.

For a better knowledge, please refer to this resource.
 
Huh :rolleyes: , thank you for answering but, let me rephrase.

I just want to know, what are fluorescent chromophores in structural sense used in fluorescent paints. By that I mean what functional element is usually used when you’re synthesizing fluorescent dye to give it characteristic known as fluorescence (and know you say something like: “it’s usually benzene ring that gives fluorescence to fluorescent dyes”).

I know almost everything about florescence as physical phenomena.


I hope that I was a little bit clearer now (this is as much as I can be, when speaking in English).
 
:) I haven’t noticed link in your reply till know, that’s helpful.
 
I want to test a humidity sensor with one or more saturated salt solutions. The table salt that I have on hand contains one of two anticaking agents, calcium silicate or sodium aluminosilicate. Will the presence of either of these additives (or iodine for that matter) significantly affect the equilibrium humidity? I searched and all the how-to-do-it guides did not address this question. One research paper I found reported that at 1.5% w/w calcium silicate increased the deliquescent point by...
I was introduced to the Octet Rule recently and make me wonder, why does 8 valence electrons or a full p orbital always make an element inert? What is so special with a full p orbital? Like take Calcium for an example, its outer orbital is filled but its only the s orbital thats filled so its still reactive not so much as the Alkaline metals but still pretty reactive. Can someone explain it to me? Thanks!!
I'm trying to find a cheap DIY method to etch holes of various shapes through 0.3mm Aluminium sheet using 5-10% Sodium Hydroxide. The idea is to apply a resist to the Aluminium then selectively ablate it off using a diode laser cutter and then dissolve away the Aluminium using Sodium Hydroxide. By cheap I mean resists costing say £20 in small quantities. The Internet has suggested various resists to try including... Enamel paint (only survived seconds in the NaOH!) Acrylic paint (only...
