Well I guess this topic is more or less related to "traditional" organic chemistry, depending on your view of the subject matter.
For the past few months I have been working on some Host-Guest chemistry. I have an organic host that I synthesized after a great deal of work, and we are hoping to incorporate a guest molecule. For what I am attempting to do, the molecule needs to have a few basic characteristics: Small Molecule, Linear Molecule, UV/VIS active, a fair amount of emission at 570nm.
So from that I know that I am probably looking for a dye molecule that is red. After looking through many different dye molecules, I believe a dye under the trade-name Methyl Red would be a good fit for our application, and Nile Red might also work. However, being size constrained many dye molecules are not applicable. I was hoping that perhaps if anyone knew any others that seem to fit perhaps they could suggest to help me out.
Also, I have looked into metal complexes that could perhaps work, so if anyone knows any that fit the criteria, please share, I am quite open to possibilities.
