What's in that new TV screen? Toward "greener" OLED's at NC State Chemistry

$800Next Goal
This project was funded on:
7 March 2014
Making new molecules that can emit light is important for improving the cost and performance of LED lighting. This project involves our recent discovery of a new method for making such materials. It is both technically simpler and creates less polluting byproducts than the current ways used to manufacture similar light-emitting compounds.


Budget Overview

The money raised in this project will be used to purchase the reaction vials used in microwave reactions. These vials comes in cases of 100 (http://cem.com/discover-sp-vessels.html) and are single use for our reaction. We anticipate using ~100 vessels a month so your funds will keep us running through the end of the Summer.

For the stretch goal of $800 we will utilize the extra funds to help fund the purchase of a gas addition kit. This will allow us to study if addition of gases such as hydrogen can be used to improve the effectiveness of our method. http://cem.com/discover-sp-accessories.html

Meet the Researcher


After graduating from Oceanview High School in Agat, Guam in 1996, Walter attended the University of Oregon. There, he received his B.Sc. in 2000 after studying he synthesis of phosphine stabilized gold nanoparticles in the lab of Prof. James E. Hutchison. From there, he went to MIT and received his Ph.D. in 2006 under the mentorship of Prof. Richard R. Schrock with a thesis that dealt with the single-site catalytic reduction of dinitrogen to form ammonia. He performed postdoctoral studies at Lawrence Berkeley National Laboratory with Dr. Heinz Frei, focusing on excited state electron transfer in silicate-based materials.
He has been at NCSU in the Department of Chemistry since 2010 where his lab develops new materials for studying how light interacts with matter.

Rewards! - At each tier you will receive, along with our thanks, the following.

$1 - We will send you an electronic copy of data produced using one of the microwave reactors along with an explanation of the experiment and the results. You will also receive an electronic copy of our first published work in this area when it comes out.

$10 - In addition to the first tier, we will send you a signed, physical copy of data produced using one of the reactors along with an explanation of the experiment.

$25 and up - Along with the previous tiers, you will receive acknowledgement in our first paper using your donation. We already did this for our first #Scifund Challenge (http://scifundchallenge.org/blog/2013/06/28/the-f...).

As soon as you make a pledge, we will contact you so you can receive your reward!

A "Stille" coupling - in this reaction the bromine (Br) and tin (SnBu3) are thrown away in order to link the two halves of the molecule.

A "McMurry" Coupling - in this reaction the only part that's thrown away is oxygen (O) in the form of water (H2O). My project follows this approach.
