Light-Emitting Polymers with Pendant Chromophoric Groups. 2. Poly[styrene-co-(p-(stilbenylmethoxy)styrene)]

Abstract

A new fluorescent polystyrene derivative is reported in which a stilbene-based chromophoric pendant group is attached on average to each third monomeric unit. Poly[styrene-co-(p-(stilbenylmethoxy)styrene)] showed fluorescence emission from intra-and interchain interaction. The model compound p-((p-ethylphenoxy)methyl)stilbene is the first stilbene derivative to show aggregate emission in solution at room temperature reported to date. It is proposed that the emission originates from the association of chromophores in the ground state forming a fluorescent dimer or aggregate complex.

Advanced syntheses and microfabrications of conjugated polymers, C60-containing polymers and carbon nanotubes for optoelectronic applications

“…SCHEME 11. [314,315]. Another interesting area closely related to the block and/or graft conjugated copolymers is the synthesis of hyperbranched/dendritic (starburst) supramolecules with conjugated moieties [316].…”

Photophysical and photovoltaic properties of a PPV type copolymer containing alternated fluorene and thiophene units

“…Typically, distances of 3.3-3.6 Å have been determined by X-ray measurements [28][29][30][31]. Since conjugated polymers are already potentially configured into a type of molecular association of sandwichtype, supramolecular structures, the formation of interchain excitons is understandably favored [32][33][34]. Due to the lower light output of the associated species relative to that of the isolated chromophores, their formation is a nondesirable event for LED applications.…”
