Studies on 3-(2-ethylhexyl)thiophene polymers
TLDR
In this article, the thermal stability of the polymers was improved due to the addition of thiophene rings with (2-ethylhexyl)thiophene, even though the absorption wavelength was red-shifted, there was no characteristic change in photoemission for the latter polymer.Abstract:
The regio-regularity and properties of the poly[3-(2-ethylhexyl)thiophene] were studied, and compared with the poly[3′-(2-ethylhexyl)-2,2′,5′,2′′-terthiophene]. The thermal stability of the polymers was improved due to the addition of thiophene rings with (2-ethylhexyl)thiophene. Due to the additional thiophenes at the 2,5 position of ethylhexylthiophene, even though the absorption wavelength was red-shifted, there is no characteristic change in photoemission for the latter polymer. Addition of thiophene rings to the 3-(2-ethylhexyl)thiophene improves the thermal properties without loosing the 3-(2-ethylhexyl)thiophene characteristics.read more

Influence of the Ethylhexyl Side-Chain Content on the Open-Circuit Voltage in rr-Poly(3-hexylthiophene-co-3-(2-ethylhexyl)thiophene) Copolymers
TL;DR: In this paper, a simple and modular model system of random copolymers based on rr-P3HT was designed to address some of these questions, and the influence of increasing amounts of branched 2-ethylhexyl side chains (10, 25, and 50%) on conjugated-polymer:fullerene solar cell performance, and especially the Voc and Jsc, was investigated.
