π-Extended Ladder-Type Conjugated Polymers via BN-Annulation
نویسندگان
چکیده
Two kinds of ladder-type conjugated polymers were concisely synthesized by the formation single-stranded via Stille cross-couplings, followed nitrogen-directed electrophilic borylations at electron-rich aromatic rings. The resulting BN-annulated show good film-forming behaviors and high air thermal stability. Their structurally shape-persistent rigid backbones render them with π-extended conjugation, allowing for efficient light harvesting in low-energy regions, emitting strong fluorescence narrow emission widths.

Diboron-containing fluorophores with extended ladder-type π-conjugated skeletons.
A series of ladder type π-conjugated diboron complexes 1-4 have been designed and synthesized by a very simple synthetic procedure. Single crystals of complex 3 were grown and the molecular structure determined by X-ray diffraction analysis demonstrated that this type of diboron ladder has a rather planar skeleton. All complexes possess very high melting points (275-383 °C) and decomposition te...
متن کاملFully conjugated ladder polymers
Fully conjugated ladder polymers (cLPs), in which all the backbone units on the polymer main-chain are π-conjugated and fused, have attracted great interest owing to their intriguing properties, remarkable chemical and thermal stability, and potential suitability as functional organic materials. The synthesis of cLPs can be, in general, achieved by two main strategies: single-step ladderization...
متن کاملCore-extended rylene dyes via thiophene annulation.
Annulation of thiophenes directly into the bay regions of rylene dyes through effective Stille coupling and subsequent ring-fusion under Scholl conditions leads to core-extended rylene tetracarboxylic diimides with interesting electro-optical properties.
متن کاملMechanically strong, fluorescent hydrogels from zwitterionic, fully π-conjugated polymers.
Mechanically strong supramolecular hydrogels (up to 98.9% water content) were obtained by the combination of a rigid, fully π-conjugated polymer backbone and zwitterionic side chains. The gels were characterized by SAXS, SEM and rheology measurements and are fluorescent, stimuli responsive (temperature, salts) and bind DNA.
متن کاملHelically assembled π-conjugated polymers with circularly polarized luminescence
We review the recent progress in the field of helically assembled π-conjugated polymers, focusing on aromatic conjugated polymers with interchain helical π-stacking that exhibit circularly polarized luminescence (CPL). In Part 1, we discuss optically active polymers with white-colored CPL and the amplification of the circular polarization through liquid crystallinity. In Part 2, we focus on the...
