Cellulose nanocrystals (CNCs) represent intriguing biopolymeric nanocrystalline materials, that are biocompatible, sustainable and renewable, can be chemically functionalized and are endowed with exceptional mechanical properties. Recently, studies have been performed to prepare CNCs with extraordinary photophysical properties, also by means of their functionalization with organic light-emitting fluorophores. In this paper, we used the reductive amination reaction to chemically bind 4-(1-pyrenyl)butanamine selectively to the reducing termini of sulfated or neutral CNCs (S_CNC and N_CNC) obtained from sulfuric acid or hydrochloric acid hydrolysis. The functionalization reaction is simple and straightforward, and it induces the appearance of the typical pyrene emission profile in the functionalized materials. After a characterization of the new materials performed by ATR-FTIR and fluorescence spectroscopies, we demonstrate luminescence quenching of the decorated N_CNC by copper (II) sulfate, hypothesizing for these new functionalized materials an application in water purification technologies.

Ternary blends comprising an ‘energy-cascade former’ in addition to the donor and the acceptor materials increasingly attract attention in the organic solar cell area as they seem to provide a tool to positively manipulate the open-circuit voltage of bulk-heterojunction devices. By comparing two additives that have similar HOMO/LUMO levels and that can be expected to lead to an energy cascade in ternaries with the prototypical P3HT:PC60BM system, we demonstrate here that the compatibility of the additive with, in this specific case, the fullerene, that can be tailored by peripheral chemical functionalization, plays a critical role in energy cascade formation. A compromise needs to be found between good mixing (favoring energy cascade formation) and phase separation (supporting charge extraction) that affect the open-circuit voltage in an as important fashion as their electronic features, providing critical insights for future materials design activities.

The photosynthetic Reaction Center (RC) from the Rhodobacter sphaeroides bacterium has been covalently bioconjugated with a NIR-emitting fluorophore (AE800) whose synthesis was specifically tailored to act as artificial antenna harvesting light in the entire visi-ble region. AE800 has a broad absorption spectrum with peaks cen-tred in the absorption gaps of the RC and its emission overlaps the most intense RC absorption bands, ensuring a consistent increase of the protein optical cross-section. The covalent hybrid AE800-RC is stable and fully functional. The energy collected by the artificial antenna is transferred to the protein via FRET mechanism, and the hybrid system outperforms by a noteworthy 30% the overall photo-chemical activity of the native protein under the entire range of visi-ble light. This improvement in the optical characteristic of the pho-toenzyme demonstrates the effectiveness of the bioconjugation approach as a suitable route to new biohybrid materials for energy conversion, photocatalysis and biosensing

A novel class of tetrathiolated aryleneethynylene oligomersud was obtained by the Cassar–Heck–Sonogashira coupling betweenud S,S'-(5-ethynyl-1,3-phenylene)bis(methylene)diethanethioateud (1) and aryl diiodides or dibromides. Althoughud standard coupling conditions are effective in the case of iodoud derivatives, the addition of free triphenylphosphane to theud reaction mixture was required to overcome the slower reactionud rate of dibromoarenes. Oligomers with an extended conjugatedud system could be obtained starting from a higher homologue of 1 by applying the same synthetic approach.ud These oligomers represent interesting molecular wires, potentiallyud able to self-assemble on various substrates, includingud gold and other noble metals in the form of thin films orud nanoparticles. The chelating arrangement of the thiol functionalitiesud should ensure stable anchoring and would alsoud represent an interesting novel feature in the study of singleud molecule conduction with respect to traditional monodentateud systems

Functionalization with fluorine atoms represents a versatile structural modification to finely tune both the emission colour and the electronic properties of organic and organometallic electroluminescent compounds. This paper reports an overview of our systematic investigation on the design and synthesis of the fluorinated version of two important classes of materials for organic light emitting diodes (OLEDs), namely poly(arylenevinylene)s and phosphorescent phenylpyridine Iridium complexes. Synthetic pathways based on organometallic methodologies affording selectively fluorinated molecular structures will be discussed together with a summary of the effect of fluorination on the optical properties of the resulting materials. In particular we will highlight the possibilities offered by the organometallic methodologies as straightforward and resourceful tools to provide a wide series of fluorinated molecular architectures with high regio- and stereoselectivity, mild experimental conditions and good yields.

The synthesis and photophysical and electrochemical characterisation of new heteroleptic iridium complexes with electron-withdrawing sulfonyl groups and fluorine atoms bound to phenylpyridine ligands are reported. The emission energy of these materials strongly depends on the position of the sulfonyl groups and on the number of fluorine substituents. A 90 nm wide tuning range of photoluminescence from the blue-green (lambda(em)=468 nm) of iridium(III)bis[2-(4'-benzylsulfonyl)phenylpyridinato-N,C2'][3-(pentafluorophenyl)-pyridin-2-yl-1,2,4-triazolate] to the orange (lambda(em)=558 nm) of iridium(III)bis[2-(3'-benzylsulfonyl)phenylpyridinato-N,C2'](2,4-decanedionate) has been achieved. Emission quantum yields ranging from 47 to 71% have also been found for degassed solutions of the complexes, and a surprisingly high value of 16% was recorded for iridium(III)bis[2-(5'-benzylsulfonyl-3',6'-difluoro)phenylpyridinato-N,C2'](2,4-decanedionate) in air-equilibrated dichloromethane. A unusual stereochemistry of the benzylsulfonyl-substituted dimer and heteroleptic complexes has been detected by (1)H NMR spectroscopy, and is characterised by the mutual cis disposition of the pyridyl nitrogen atoms of the phenylpyridine ligands, which differs from the most common trans arrangement reported in the literature.

Organic thin-film transistor sensors have been recently attracting the attention of the plastic electronics community for theirud potential exploitation in novel sensing platforms. Specificity and sensitivity are however still open issues: in this respect chiralud discrimination—being a scientific and technological achievement in itself—is indeed one of the most challenging sensor bench-tests.ud So far, conducting-polymer solid-state chiral detection has been carried out at part-per-thousand concentration levels. Here, a novelud chiral bilayer organic thin-film transistor gas sensor—comprising an outermost layer with built-in enantioselective properties—isud demonstrated to show field-effect amplified sensitivity that enables differential detection of optical isomers in the tens-of-parts-permillionud concentration range. The ad-hoc-designed organic semiconductor endowed with chiral side groups, the bilayer structure andud the thin-film transistor transducer provide a significant step forward in the development of a high-performance and versatile sensingud platformcompatible with flexible organic electronic technologies
