n this presentation, we introduce our recent accomplishments
on the integration of tailor-designed polymers for diverse
applications. Hybrid plasmonic nanostructures comprising Au
nanoparticle arrays separated from Au substrate through a
temperature-sensitive poly(N-isopropylacrylamide) linker layer
were constructed, and a unique plasmonic-coupling-based
surface plasmon resonance sensing properties and visible
light active photocatalysis were investigated. Multimetallic
Core@Shell nanoparticles consisting of Au core and metal-
containing polyaniline shells were prepared and their bifunctional
electrocatalytic performance was systematically investigated.
Well-defined ordered arrays of plasmonic nanostructures were
fabricated on stretchable poly(dimethyl siloxane) substrates
and tunable plasmon-coupling-based sensing properties were
comprehensively demonstrated upon extension and contraction.
We studied phosphorescence emission enhancement of a purely
organic phosphor system via plasmon resonance energy transfer
by precisely tuning the distance between purely organic phosphor
crystals and plasmonic nanostructures using layer-by-layer
assembled polyelectrolyte multilayers as a dielectric spacer. We
demonstrate a viable laser interference lithography technique
enabling the development of high-performance plasmonic organic
photovoltaic (OPV) devices. Ag nanodot arrays with optimized
configuration embedded in poly(3,4-ethylenedioxythiophene):pol
y(styre-esulfonate) hole transport layer remarkably enhanced the
average power conversion efficiency by ~34.4% compared to the
pristine device. Hierarchically organized porous carbonized-Co

inverse opal nanostructures were synthesized via complementary
colloid and block copolymer self-assembly, where the triblock
copolymer Pluronic P123 acts as the template and the carbon
source. These highly ordered porous inverse opal nanostructures
with high surface area display synergistic properties of high energy
density and promising bifunctional electrocatalytic activity toward
both the oxygen reduction reaction and oxygen evolution reaction
in Li-air battery.
