I've recently taken an interest in various substances called organogels. I've not found this term discussed much on this forum, but I know they exist
after reading a variety of research papers. I've attempted to understand the various trends amongst organogels and what enables them to uptake various
organic solutions, solvents, and substances and embed them into the organogel matrix. However, I haven't come across enough information about trends.
From what I've come to understand, it generally has to do with the polarity of the molecule and the polarity of the matrix. Varying lengths of the
organogel substance are also involved. Another big thing to consider is the boiling point of the substance of the matrix being used. However, I'm
unsure as to whether or not an organic substance can remain as a solution yet have the organogel solution boiled and then have the organic solution
embedded into the organogel.
It seems like much of this research is done in Japan, at least much of what has interested me as of late. However, I can't seem to understand many
patterns nor trends: Perhaps this is because organogels are a hot research topic right now and the researchers are still trying to make sense of it
all.
Do any of you forum members know much about organogels, their fundamentals, and how to choose a particular organogel for a particular organic molecule
type?

And where are these references?
You open a topic, but you don't give a single reference to start a discussion. It is up to you to do the initial literature work or else this thread
will go nowhere.dennisfrancisblewettiii - 17-8-2012 at 22:20

Those are three articles that interested me and saved to my zotero, but I'm still hoping there may be other users here with previous knowledge of
organogels and their workings.

Although supramolecular organogel preceded supramolecular hydrogel in their development, it is still hard to establish a rational strategy for
designing a supramolecular organo- or hydrogelator.

Are these 'organogels' that you are talking about anything like the hydrogels in this paper below?

This is a very all encompassing topic, some of the technologies which are proprietary. Not just acrylate polymers which soak up to 200X their mass in
water. There are systems which act like blown foam. Some of the fall-backs have the organic solvent dissolving part of the matrix, and forming a
slush out of what was a gel.
I can offer some high lights, but am no expert in the technology. Polymer technology goes hand in hand.
