“…[172] White PLEDs were also fabricated from polystyrene random-copolymers with different dithienophosphole oxide functional groups as side chains. [173] Theu se of arsenic in p-conjugated hybrid systems comes with some significant advantages due to the lower oxophilicity,t he higher polarizability,a nd the enhanced electron affinity. [174] Especially appealing is the oxidative stability, which is related to the poor shielding of the filled 3d orbitals in As that renders the s-electrons to be more tightly bound.…”

The past decade has witnessed tremendous advances in the synthesis of polymers that contain elements from the main groups beyond those found in typical organic polymers. Unique properties that arise from dramatic differences in bonding and molecular geometry, electronic structure, and chemical reactivity, are exploited in diverse application fields. Herein we highlight recent advances in inorganic backbone polymers, discuss how Lewis acid/base functionalization of polymers results in unprecedented reactivity, and survey conjugated hybrids with unique electronic structures for sensor and device applications.

“…Examples have surfaced within the past few years in utilizing main group elements in the construction of OLEDs and within catalysis/small molecule activation by taking advantage of the unique properties that these main group centres posses. [11][12][13][14][15] Efforts in these fields by ourselves and other research groups have centred on designing new ligand sets containing thiophene, a ubiquitous building block in the area of redox active and fluorescent materials. 16,17 Ultimately such architectures target the photoluminescent and polymerizable properties of thiophene, yet look to tune the photophysics of the overall construct by varying the main group element centre.…”

A phosphenium cation supported by a seven-membered thiophene based ring system

A novel diamine ligand containing a simple thiophene ring in the backbone has been synthesized. Substitution at the nitrogen atoms with either 2,4,6-trimethylphenyl (Mes) or 2,6-diisopropylphenyl (Dipp) was varied via a condensation reaction between the corresponding aniline and 3,4-diformylthiophene, giving two different ligand derivatives. In onwards chemistry that targeted the cyclic diaminochlorophosphines, the substitution at phosphorus was dependent on the ligand used. For example, when a stoichiometric reaction between PCl 3 and thiophene-3,4 diyldimethaneamine (R = Mes) was carried out, the synthesis of a bis-substituted diphosphino-product was isolated. If the R = Dipp ligand derivative was employed, both a 2:1 and 1:1 stoichiometric reaction between PCl 3 and the diamine was observed. Nevertheless, the cyclic diaminochlorophosphine (i.e., 1:1 stoichiometry) for R = Dipp was isolated in high yields and the synthesis of the corresponding phosphenium cation was achieved and structurally characterized.Résumé : On a synthétisé un nouveau ligand diamine dont le squelette contient un noyau thiophène simple. On a procédé à la substitution d'un groupe 2,4,6-triméthylphényle (Mes) ou d'un groupe 2,6-diisopropylphényle (Dipp) sur les atomes d'azote par une réaction de condensation entre l'aniline correspondante et le 3,4-diformylthiophène pour obtenir deux dérivés différents du ligand. Lors de réactions chimiques ultérieures ayant pour cible les diaminochlorophosphines cycliques, la substitution sur le phosphore dépendait du ligand utilisé. Par exemple, une réaction stoechiométrique entre PCl3 et la thiophène-3, 4 diyldiméthanamine (R = Mes) a donné la synthèse d'un produit diphosphiné bisubstitué. Lorsqu'on a employé le dérivé R = Dipp du ligand, on a observé une réaction de stoechiométrie 2:1 ainsi qu'une réaction de stoechiométrie 1:1 entre PCl3 et la diamine. Néanmoins, on a isolé avec un haut rendement la diaminochlorophosphine cyclique (c. à d. stoechiométrie 1:1) obtenue pour R = Dipp, et on a synthétisé le cation phosphénium correspondant et caractérisé sa structure.

“…Various kinds of polymer have been synthesized in order to prepare white-light emitting materials [16][17][18][19]. Normally, blue, green, and red are the basic colors required to obtain white-light emission [20,21]. Two complementary color molecules are also good choices [22][23][24].…”

An effective method to prepare polymer/nanocrystal composites with tunable emission over the whole visible light range

et al. 2010

Materials with emission over the whole visible range (400-800 nm) have been obtained through incorporating single-colored CdTe nanocrystals (NCs) into a poly(p-phenylene vinylene) (PPV) precursor [the sulfonium polyelectrolyte precursor of PPV]. Firstly, the quantum yield (QY) of the PPV precursor was improved to ~50% via heat treatment of a mixed solution of the PPV precursor and poly(vinyl alcohol) (PVA) at 100 °C for 3 min. Then, single-colored CdTe NCs were incorporated into the mixed solution. The introduction of the PVA was necessary to reduce the electrostatic interaction between the PPV precursor and CdTe NCs, which improved their compatibility. The reduced electrostatic interaction eliminated Förster resonance energy transfer (FRET) processes between NCs, as well as between NCs and the PPV precursor, which allowed the functional integration of the polymer and NCs. Consequently, polymer/NC composites with almost any Commission Internationale de L'Eclairage (CIE) coordinates can be achieved by simply changing the size and amount of the NCs. In particular, when the emission wavelength of the CdTe NCs was 559 nm, a pure white-light emitting material with CIE coordinates (0.337, 0.332) was obtained.
