of aggregation of the PTDAP chains. According to the above PL
results, we anticipated that incorporation of PVBU into PTDAP,
which contains chromophoric polythiophene segments, would
exhibit improved PL quantum efficiency (PLQE) of its thiophene
units. The PLQE of the 5/95 PTDAP/PVBU fiber is 0.21, which
is substantially higher than that of the 5/95 PTDAP/PS fiber
(PLQE = 0.12) (Table 1). Further increasing the PTDAP content to
50 wt% resulted in the increase in the PLQE value to 0.68,
whereas the emission quantum yield of the 50/50 PTDAP/PS fiber
is only slightly increased to 0.23 (Scheme 1). These results further
demonstrated that incorporation of PVBU into PTDAP significantly
influences the photophysical properties of the luminescent electro-
