This paper describes the synthesis of aromatic ladder polymers containing main chain 2,5-thienylene moieties. A suitably substituted single-stranded intermediate of these novel poly(1,4-phenylene-2,5-thienylene) ladder polymers (LPPPT) was created by

Noise current analysis, both in time and frequency, is proposed as a means to sense variations of the microscopic conduction in organic light emitting diodes and to track their time evolution. The sensitivity of the technique would allow to correlate

We report on temperature (104K - 575K) dependent Raman investigations of two ladder type poly(paraphenylenes), LPPP and mLPPP. This temperature range is important for applications in light emitting devices. A usual weak softening with increasing temp

We report the electrical characteristics of light emitting electrochemical cells (LECs) consisting of a wide band gap light emitting polymer, mLPPP, (methyl substituted ladder type poly(paraphenylene)) and Li-triflate based solid state electrolytes u
