Concept of donor-acceptor SMAs

We succeeded in synthesis of donor-acceptor block copolymer supramolecular assemblies (SMAs) with two classes of additives – precursors of conjugated polymers and electro-luminescent oligomers. Both kinds of SMAs reveal well defined nanoscopic domains (dots or cylinders) of electroluminescent additives distributed in block-copolymer matrix with the periodicity of 25 - 40 nm. The next phase of the project will consist in investigation of optoelectronic properties of the SMAs. This research will make fundamental contributions to the area of supramolecular assemblies thereby enabling applied advancements in energy conversion materials and fabrication of optoelectronic devices Concept of donor-acceptor SMAs AFM images of several SMA (films)

Optoelectronic Supramolecular Block-Copolymer Assemblies Aided by Donor-Acceptor Interactions Alexander Sidorenko, University of the Sciences in Philadelphia, DMR 0947897 One graduate and three undergraduate students are involved in the research related to the project at USP. This work has strengthened their competence in different fields of polymer science, physical chemistry, organic synthesis, and related equipment/instrumentation. The students participated in the Research Day-2010 at USP and the Mid-Atlantic Regional Meeting of ACS. As a result of our efforts to involve traditionally underrepresented groups in the research, two women and one African American student conduct research in Sidorenko’s group. The results have been disseminated at several scientific meetings including research seminars at Clemson University and the Bristol-Myers Squibb Co. Prospective collaborative projects with BMS and Velmex, Inc. have been discussed. The positive impact on the infrastructure at USP includes conductive mode AFM accessory purchased recently. In April of 2010 the PI together with several other faculty members organized the Chemistry for Kids Day. This event went by very well and has been considered to be performed on a regular basis. Sidorenko has developed a new course in Polymer Science (specially designed for undergraduate and graduate students) for the first time in USP.
