BDT Based Polymers in OFET Application

BDT isomers and related polymers have recently been developed by Mullen and co-workers [41,42]. Depending upon the geometrical arrangement of the thiophene units and the benzo unit in the fused 

Polymer Monomer Angle Backbone Amplitude Wave Length 

Specifically, to improve the power conversion efficiency of polymer-based BHJ photovoltaic cells, one has to carefully address the following three issues  

To summarize, in order to exhibit high photovoltaic properties, the ideal polymer should have (a) good solubility (b) high molecular weight (c) HOMO level around - 5.4 eV (d) a narrow band gap around 1.5 eV (e) a high hole mobility and (f) an optimized
