Conjugated Molecules or Polymers

Description

We are interested in the broad areas of synthesis and properties of organic conjugated molecules for electronic applications.  Specifically, we are interested in controlling the molecular structure and molecular packing of conjugated organic molecules and problems.  For example, we are interested in controlling molecular assembly over multiple length scales and obtaining morphologies that are difficult to obtain using existing tools for self-assembly or with desired organic materials.

Poly((2-Alkylbenzo[1,2,3]triazole-4,7-diyl)vinylene)s (pBTzVs) synthesized by Stille coupling show different absorption spectra, solid-state morphology, and photovoltaic performance, depending on straight-chain versus branched-chain (pBTzV12 and…

Quaterthiophene (QT) with a 1,2,3-triazole moiety was found to have a high sensory response in solution toward a broad class of nitroaromatics, including DNT and TNT, and nitro esters, such as RDX and PETN. Fluorescence quenching in QT thin films was…

3,6-Bis(N,N-dianisylamino)-fluoren-9-ylidene malononitrile (FMBDAA36) was used as an electron donor material in solution-processed organic photovoltaic devices with configuration ITO/PEDOT:PSS/(1:3[w/w] FMBDAA36:PC71BM)/LiF/Al to give power…
