Abstract

Conjugated polymers are a new class of material that can combine the electronic and optical of inorganic compound semiconductors with the ease of processing and mechanical manipulation of plastics[1] It has been demonstrated for some time that the donor (p-type) conjugated polymers help stabilize and transport the positive charges (holes), and acceptor (n-type) conjugated polymers help stabilize and transport the negative charges (electrons), thus photo induced electron transfer and charge separation observed in organic composites of donors and acceptors offeres a potential organic molecular approach to high efficiency light harvesting or opto-electronic applications[2, 3] In the following experiments, the donor block (D) is an alkyloxy derivatized polyphenylenevinylene or "RO-PPV", the acceptor block (A) is an alkyl-sulfone derivatized polyphenylenevinylene or "SF-PPV". The bridge unit that was studied was a diamine terminated bridge unit. The synthesis of 2-ethyl-hexyl derivatized RO-PPV and SF-PPV conjugated blocks, and the synthesis of dialdehyde bridged --DBAB- have been recently presented [4], The synthesized --DBAB- has been characterized by NMR, GPC, MALDI, thermal analysis, electrochemical analysis, electrical conductivity, electron microscopy, etc [12]. The studies of --DBAB- morphology of the thin films and the photoluminescence, and luminescence lifetime are presented.
