Abstract
FDT and FDT-Br diradicaloids with stable coexisting close-shell and open-shell forms exhibit unconventional self-doping behavior in solid-state electronic devices that is temperature (T) tunable and reversible. The doping is strengthened by the increased T, leading to the absence of off-states (I(off)) in the transistors.

Abstract
Rational materials design and interface engineering are both essential to realize a high performance for tandem cells. Two identical bulk heterojunctions are connected in series using novel interconnection layers combining pH-neutral conjugated polyelectrolytes and a thin film of ZnO nanoparticles by a solution process. The best performing tandem cells achieve a power conversion efficiency of 11.3%, with 25% enhancement in efficiency compared with single cells, which arises primarily from the increased light absorption.

ADVANCED MATERIALS (DEERFIELD BEACH, FLA.) 2014; 26:4697-703.

Abstract
Two narrow-bandgap conjugated polyelectrolytes (CPEs) of identical backbone structure but different pendant charges are used to disperse single-walled carbon nanotubes (SWNTs) in MeOH. Films of the resulting CPE:SWNT composites have electrical conductivity dependent on the SWNT loading, which can be increased with acid vapor treatment. The anionic CPE gives higher electrical conductivity for the composite immediately after deposition, whereas a more-significant increase is observed for the cationic counterpart after acid treatment.
