You have a Masters or PHD in Chemistry. You like drawing chemical structures and searching for them on the internet (I do too!) We have about 20 patents about dichroic dyes. (Note that most of these dyes date from 1980, and are now part of the public domain.) This easy project reviews the patents and estimates the feasability of synthesizing the dyes. The primary challenge is that these dyes are really obscure, really arcane. In many instances these dyes are so obscure that they are not included in CA. Likwise the precursor chemicals are often not stock chemicals. The precursors need to be synthesized first, then the dyes. You will review the dyes and will analyze them for feasability, given the usual feasability considerations and more : Waste disposal cost Chemist safety Precursor materials safety End product consumer toxicity Labor cost to synthesize Dye order parameter Yield Compatible with the liquid crystal host You may write pithy comments about each individual dye product on to the patent sheets for efficiency. I do not need a formal report prepared. Your comments written directly onto the actual patent sheets should be sufficient. You will complete the project within 14 days of acceptance. IN YOUR REPLY TO THIS POSTING, PLEASE ANSWER THE FOLLOWING SCREENING QUESTION : CO makes lots of smiles. What is CO? Thank you for reading this posting. Allen.

Dear Sir or Madam, I have PhD in chemistry. I was running R&D lab in household chemistry and cosmetics for over a year. Later I was working as team leader in medicinal chemistry lab. Currently I work as freelancer providing articles, reviews and know-how from the fields like biology, chemistry and medicine. I have 8 years of experience at University, 3 years in private R&D labs followed by 5 years of freelancing as a consultant. I can assess: Safety Toxicity Yield Maybe compatibility with liquid crystals Rough estimate of materials required for the synthesis Synthetic costs and waste management will depend on the scale of the production, therefore they cannot be assessed. Answering your secret question, I'd say you made a mistake, it should be NO not CO. Kind Regards Chris
