“…Yue et al. also used ZnO nanorod arrays to improve electron extraction from an MEH-PPV-CIS BHJ architecture, and reached a PCE of 2.54% under monochromic illumination at 470 nm . Yue et al used a TiO 2 nanowire array to improve electron transport to the current collector in HSCs in a similar BHJ architecture and reached PCEs up to 1.6% .…”

This review captures the synthesis, assembly, properties, and applications of copper chalcogenide NCs, which have achieved significant research interest in the last decade due to their compositional and structural versatility. The outstanding functional properties of these materials stems from the relationship between their band structure and defect concentration, including charge carrier concentration and electronic conductivity character, which consequently affects their optoelectronic, optical, and plasmonic properties. This, combined with several metastable crystal phases and stoichiometries and the low energy of formation of defects, makes the reproducible synthesis of these materials, with tunable parameters, remarkable. Further to this, the review captures the progress of the hierarchical assembly of these NCs, which bridges the link between their discrete and collective properties. Their ubiquitous application set has cross-cut energy conversion (photovoltaics, photocatalysis, thermoelectrics), energy storage (lithium-ion batteries, hydrogen generation), emissive materials (plasmonics, LEDs, biolabelling), sensors (electrochemical, biochemical), biomedical devices (magnetic resonance imaging, X-ray computer tomography), and medical therapies (photochemothermal therapies, immunotherapy, radiotherapy, and drug delivery). The confluence of advances in the synthesis, assembly, and application of these NCs in the past decade has the potential to significantly impact society, both economically and environmentally.

“…Poly(phenylenevinylene) (PPV) and its derivatives have attracted considerable attention because of their remarkable optical and electronic properties. It is well known that after the discovery of the optoelectronic properties of PPVs, especially the electroluminescence, , these materials have been exploited as an active layer in organic light-emitting diodes (OLEDs) − and other applications such as laser dyes, − photovoltaic cells, − chemosensors, − linkers for metal–organic frameworks (MOFs), − dendrimers, − photoredox catalysts, and photosensitizers. − The synthesis of PPVs frequently presents challenges as it leads to a mixed cis/trans-configuration over the vinyl segments of the polymeric structure; they show large dimensions and poor solubility in a wide range of solvents …”

Spectroscopic and Time-Dependent DFT Study of the Photophysical Properties of Substituted 1,4-Distyrylbenzenes

In this contribution, we examine the photophysical properties of 15 totally trans–trans 1,4-distyrylbenzene derivatives (DSBs) functionalized with different electron-donating (ED) and electron-withdrawing (EW) groups by experimental and computational methodologies. We use UV–vis and fluorescence spectroscopies to determine the experimental optical properties such as the maximum absorption (λabs exp) and emission (λem exp) wavelengths, the highest occupied molecular orbital–lowest unoccupied molecular orbital (HOMO–LUMO) energy gaps (ΔE abs exp), the molar extinction coefficients (ε), the fluorescence quantum yields (Φf), and the fluorescence lifetimes (τ). We also calculate the experimental spontaneous emission decay rate (k r exp) and correlate all of these magnitudes to the corresponding calculated properties, maximum absorption (λabs cal) and emission (λem cal) wavelengths, vertical transition energies (ΔE abs cal), oscillator strength (F osc), and spontaneous emission decay rate (k r cal), obtained by the time-dependent density functional theory method. We analyze the effect of the electronic nature of the substituents on the properties of the DSBs, finding that the ED and EW groups lead to bathochromic shifts. This is consistent with the decrease of ΔE values as the strength of ED and EW substituents increases. We find excellent correlations between calculated and experimental values for λabs, λem, and ΔE abs (r ∼ 0.99–0.95). Additionally, the correlations between the relative ε with F osc values and the k r values are in good agreement (r ∼ 0.88–0.72) with the experimental properties. Overall, we find that for substituted 1,4-DSBs, computational chemistry is an excellent tool to predict structure–property relationships, which can be useful to forecast the properties of their polymeric analogues, which are usually difficult to determine experimentally.
