| Abstract: | Bio-derived optoelectronic material is captivating and sustainable research as it reduces the environmental toxicity and comforting the wearable aspects. Our research involves the synthesis of series of bio-derived polyfluorene-block-poly(delta-decanolactone) (PF-b-PDL) conjugated block copolymers through smart one-pot procedure that involves simple purification for fabricating touch-responsive light-emitting diode (LED) devices. Compared with PF homopolymer, the block copolymers exhibit higher photoluminescence quantum yields and higher exciton binding energies. PF18-b-PDL13 specifically exhibits external quantum efficiency (EQE %) (similar to 6 times higher than PF homopolymer). Moreover, because of coily PDL block inducing a highly stable bound state in block copolymer generating the increment in PL lifetime and exciton binding energies than the homopolymer. Furthermore, the diblock copolymers device exhibits fully solution processability, higher carrier recombination efficiency, flex-stretch stability, good structural integrity and mechanical endurance highlighting the brighter potential of our bio-derived block copolymers for fabricating highly durable wearable stretchable nano and microelectronic devices. |
