We introduced a dual electron accepting layer composed of tetrafluoro-tetracyanoquinodimethane (F-4-TCNQ) and MoO3 for thermoelectric devices based on a pentacene layer. We found that the power factor is enhanced by placing an F-4-TCNQ layer direc...
Comparative studies of the effects of a series of polycrystalline donors on the performance of 95 wt.%-C-70-based bulk-heterojunction (BHJ) photovoltaics were conducted. A BHJ based on the wide band-gap molecule dinaphthothienothiophene (DNTT) sho...
A post-synthetic method has been developed to synthesize novel asymmetric porphycenes bearing two different substituents on the meso-positions. Nitration of 9-acetoxy-2,7,12,17-tetra-n-propylporphycene with AgNO3 in CH3COOH/CH2Cl2 occurs regiosele...
A linear-shaped phosphorescent platinum(II) complex that adopts a horizontal orientation in amorphous films was synthesized. The complex possesses a photoluminescence quantum efficiency of Phi(PL) = 50 +/- 3% in thin films with the host of m-bisca...
