    PE ,

    Here are the 5 dyes from your list from first to fifth.
    Are they enough to solve rgb sensitization or do I need to continue ?

    Umut;

    It would take me a while to work out the structure, and I doubt if it would do anyone any good.

    As for providing R/G/B sensitivity, we do have dyes already posted here that do the trick and so I have no concern about it being a problem. Except for the cost, these dyes are available.

    Now, as to their working, some dyes work and some do not on any given emulson. I have 5 or 6 dyes that I tried and got 2 that work on all emulsions, but one is weak and the other sensitizes at a long green wavelength. Another one only works well on bromide emulsions as a green but works on bromo / iodide emulsions as either a red or green. This dye has been the subject of much discussion here.

    So, I cannot answer your question about "solving the problem" until I did an experiment with at least 3 emulsions with each dye. You can see how time consuming and expensive that will be. I've already done the ones about, 6 or 7 dyes with 3 emulsions and have published the good results either here or in the book.

    Ok, here we go, a proof of concept... $52/gram, minimum order of $100.

    http://chemicals.citychemical.com/it...origin=keyword

    Now, of course there's a lot more to consider here, like Ron says, but with a little effort and creativity I think we can find sensitizers that won't break the bank, hopefully one that does a good job with red.

    Umut, awesome job. However, is it necessary to copy and paste all of that?!

    I got some cryptocyanine from Sigma-Aldrich 1½ years ago, the price was 43 EUR (about 55 USD) for 250 mg. As you might guess, I haven't got time to test it.

    So, that one looks quite a bit more attractive, given the much lower price and the fact that buying from Sigma-Aldrich may not be very straightforward (at least you need a company).
