“…In addition, carrier mobility of Az-PPV was similar. The values were higher than those of the reported PPV derivatives [92][93][94] and the other conventional π-conjugated polymers. [95][96][97][98] Therefore, it is proposed that introduction of the N=N double bonds might be effective for enhancing career mobility of π-conjugated polymers.…”

Azomethine (C=N) and azo (N=N) scaffolds are a part of structural units in poly(p‐phenylene azomethine) (PAM) and poly(p‐phenylene azo) (PAZ), respectively. Poly(p‐phenylene vinylene) (PPV) is known to be one of luminescent π‐conjugated polymers, meanwhile PAM and PAZ, which are the aza‐substituted PPV analogues, are regarded as weak or no emissive materials. However, by the boron complexation, intense emission can be induced. Furthermore, environment‐sensitivity and stimuli‐responsivity were also observed. In this review, we demonstrate unique and versatile luminescent properties based on “flexible and bendable” π‐conjugated systems composed of the boron‐fused azomethine and azobenzene complexes (BAm and BAz) with the O,N,O‐type tridentate ligands. The “flexible and bendable” luminophores showed intriguing optical behaviors, such as thermosalient effect, aggregation‐induced emission (AIE) and crystallized‐induced emission (CIE). Moreover, highly efficient emissions both in solution and film states were observed from the polymers. We illustrate the results and mechanisms on these luminescent properties from the series of our recent studies with BAm and BAz complexes and polymers.

“…This observation is attributed to the field dependence of the carrier drift length, as has been found elsewhere [7,22]. The transient photocurrents in our devices exhibit some dispersive behaviour, which is commonly observed in polymer-based systems [7,8,[22][23][24]. An effective lifetime (τ) was found on a double logarithmic plot as the intersection of asymptotes to the plateau and the linear region of transient's trailing edge [25,26], as is shown in the inset of Figure 2A.…”

The photovoltaic response of symmetric sandwich polymer cells based on poly[5-(2′-ethylhexyloxy)-2-methoxy-1,4-phenylene vinylene] (MEH-PPV) and MEH-PPV:fullerene blends has been investigated. Identical, semitransparent gold, silver, aluminum, and calcium are used as top and bottom electrodes. Most of the nominally symmetric sandwich cells exhibit pronounced photovoltaic (PV) response. The PV parameters are strongly dependent on the direction of illumination, the active layer thickness, and the evaporation rate of top electrode. Open-circuit voltage as high as 0.7 V has been measured in silver/MEH-PPV/silver cells. The addition of fullerene leads to reduced open-circuit voltage and higher short-circuit current. The photovoltaic response observed in these nominally symmetric sandwich cells is attributed to their different top and bottom electrode interfaces.
