Disadvantages of Traditional Electronics:
1. Lack Of Sustainability Prospects
2. High Manufacturing Costs
3. Complex Processing
4. Rigid Substrates
5. Small Usable Surface Areas
Sustainability being the talk of the town and Moore's Laws’ increasing relevance evidently imply that the future is
going to be ORGANIC ELECTRONICS . . . .
What is Organic Electronics ?
Organic electronics is the branch of Material Sciences which
involves the use of conducting Organic Polymers and their
small monomer molecules in designing electronic circuits.
Most of these polymers and monomers are carbon based and
hence this new technology is termed as Organic Electronics.
Though it is also known as Plastic or Polymer Electronics in
the Scientific fraternity. This is a modern revolutionary tech-
nology involving the charge transfer complex formation
properties of organic polymers.

Alpha-Oligofurans: The Future….
 α-Oligofurans are a new class of organic compounds with long chains of as
much as nine rings attached to one other.
 Oligofurans are highly fluorescent with a quantum yield of 58-74 % which is
far more than contemporary LED materials.[2]
 They are stronger and more rigid than the sister class of compounds Oligothio-
phenes and yet more soluble in suitable substrates thus is the best material
known for flexible devices.
 The electronic coupling integral of oligofurans (Hab) is 30-40% greater indicat-
ing better conductivity than graphene.
 The high conductivity of oligofurans along with a higher HOMO-LUMO gap
serves a great deal in its use as a replacement of semiconductors.
 The long chain of Oligofurans provide a large surface area at the nano level thus
increasing
