“…Among the various types of azo-benzenes, azo-pyridines (AzPy) find frequent use in crystal engineering − as good hydrogen or halogen bond acceptors and coordination ligands. This property is extensively employed in building supramolecular assemblies, − metal–organic frameworks (MOFs), − and cocrystals. , …”

Azo-pyridinic derivatives are renowned for their ability to undergo reversible molecular switching when exposed to light. By combining the photoresponsive properties of azo-benzene with the supramolecular capabilities of pyridyl groups, azopyridines offer a route to develop multifunctional responsive materials through noncovalent interactions or reversible chemical reactions. Although azo-pyridine and its derivatives are commonly used in crystal engineering, their spectroscopic characterization is typically limited in solution and only poor attention has been given to their photoresponsive behavior in the solid state. Here, we present a library of azo-pyridinic derivatives designed as potential photoresponsive compounds with different spectroscopic behaviors based on the chemical decoration of the phenyl ring. Comprehensive characterization, including crystal structure, thermal analysis, and spectroscopic analysis, was performed for all compounds. Finally, their trans-to-cis isomerization propensity in the solid state is correlated with their crystal structures.

“…[2][3][4] MOFs are potentially porous coordination networks composed of metal nodes, often reported as secondary-building-units (SBUs), and polytopic linkers. 5 The crystallinity of MOFs and the knowledge of their precise crystalline structure enable the design of new architectures and the development of new functional materials that make MOFs highly attractive in several applications, such as gas storage and separation, [6][7][8][9][10] guest-inclusion, [11][12][13][14][15] development of electronic materials, 16,17 food 18 and environmental 19 control and heterogeneous catalysis. [20][21][22][23] Among the physical properties that can be imparted to MOFs, luminescence covers a prominent role in the development of responsive crystalline materials.…”

“…It has been applied to the analysis of PAHs in several matrices, both in immersion and head space (HS) modes [ 19 ]. The vast majority of the works regard water samples, with a range of diverse coatings tested, such as the conventional polydimethylsiloxane (PDMS) [ 20 , 21 ] or novel materials such as graphitic carbon nitride [ 22 ], carbon nanotubes [ 23 ], and metal-organic frameworks (MOFs) [ 24 , 25 ]. Regarding plant matrices, HS-SPME has been widely employed for a range of compounds, especially those giving the aromatic profiles [ 26 ].…”

Solvent-Free Determination of Selected Polycyclic Aromatic Hydrocarbons in Plant Material Used for Food Supplements Preparation: Optimization of a Solid Phase Microextraction Method

The exploitation of waste and by-products in various applications is becoming a cornerstone of the circular economy. A range of biomasses can be employed to produce food supplements. An example is a particular extract obtained from plant buds (rich in bioactive molecules), which can be easily retrieved from cities’ pruning. In order to safely use this material, its possible contamination by organic pollutants needs to be estimated. A green and simple method to detect priority polycyclic aromatic hydrocarbons (PAHs) in bud samples by head space solid phase microextraction coupled to GC-MS was developed. This strategy, optimized through experimental design and response surface methodology, requires a minimal sample pre-treatment and negligible solvent consumption. The final method was found to be accurate and sensitive for PAHs with mass up to 228 Da. For these analytes, satisfactory figures of merit were achieved, with detection limits in the range 1–4 ng g−1, good inter-day precision (relative standard deviation in the range 4–11%), and satisfactory accuracy (88–105%), along with specificity guaranteed by the selected ion monitoring detection. The method was applied to bud samples coming from differently polluted areas, thus helping in estimating the safety of their use for the production of food supplements.
