Sensing analysis is significantly important for human health and environmental safety. In this review, POPs used as platforms for various sensing applications have been summarized and discussed.

A new Pd-catalyzed reaction of thiophenes with alkynes via C-H and C-S bond activation has been developed. This provides a new approach to prepare sulfur-containing compounds. An interesting salt effect was observed, and the reaction's efficiency and selectivity depend not only on the type but also on the amount of the salt used.

A series of intensely blue fluorescent BN-embedded tetraphene derivatives have been synthesized by the catalytic cyclization of BN-naphthalenes with alkynes. The BN-tetraphene can be selectively functionalized to give a substituted derivative via bromination followed by a cross-coupling reaction. The electronic and photophysical properties of the novel BN-tetraphene system were investigated using UV-vis and fluorescence spectroscopy, electrochemical cyclic voltammetry, and DFT calculations, which disclosed its distinct electronic and photophysical properties from the analogous hydrocarbon system.

As eries of novel BN tetraphene derivatives have been prepared successfully for the first time via ap ostfunctionalization strategy.T he optical and electronic properties of these derivatives could be tuned systematically by the incorporation of different substituents on the main skeleton. The functionalizedB N-containing luminogens have been explored for the detection of latent fingerprints (LFPs) on different substrates,including glass,aluminum foil, plastic, and ironware.T his strategy provides great versatility in LFP imaging and good potential in elucidating the chemical information within LFPs,m aking the strategy valuable in forensic investigations.The incorporation of main-group elements into polycyclic aromatic hydrocarbons (PAHs) is ap romising strategy for modulation of the photophysical and electronic properties of materials. [1] One appealing approach is the replacement of one or more C = Cbonds in PA Hs by isosteric BN pairs,which may significantly modify the chemical and electronic properties of the molecule due to the polarization of the B À Nbond while maintaining the aromaticity and basic structural features of the original compounds. [2][3][4] Indeed, this strategy has enriched the family of PA Hs with modulated properties. However,the real applications of the materials still remain an unknown proposition, because their stability and sensitivity to ambient conditions are important. Moreover,a nother primary reason is the lack of available synthetic routes to produce large amounts of these materials.T oour knowledge, so far, the synthetic strategies are quite limited and they usually rely on classical electrophilic borylations performed under harsh conditions.T herefore,s uitable methodology is needed to enrich the chemical diversity of BN-containing compounds,which not only provides the possibility to explore the performance of these materials in device applications,but also renders the opportunity to systematically study their structure-property relationships.T he selective late-stage functionalization is the most general and efficient approach to achieve chemical diversification and to fine-tune the molecular properties of functional molecules. [5] However, little attention has been paid to applying this approach to BNdoped aromatic compounds,e specially BN-modified conjugated molecules. [6] Thepotential of this strategy in extending the p conjugation and modulating the optical and electronic properties or other functional properties of am olecule has not been fully investigated yet.As mentioned above,m ost boron-containing compounds are air-a nd moisture-sensitive due to the inherent electron deficiencyo ft he boron atom. Therefore,n ew strategies are quite beneficial to stabilize the boron center.T he most common strategy is to use sterically bulky groups to kinetically stabilize the boron center, [7] but this is at the expense of preventing solid-state p-p stacking.I nr esponse to these limitations,a ne xciting concept for stabilizing organoboron compounds was introduced by Yamaguchi and P...

A one-stone-two-birds strategy including simultaneous exploration of reactivity and tuning of the optical and electronic properties for BN-fused polycyclic aromatics through flexible regioselective functionalization engineering is presented.

Herein, a Pd-catalyzed reaction of simple and diverse bromothiophenes with alkynes via regioselective C-S bond activation is reported. This provides a new approach to prepare sulfur-based heterocycles and fulvenes.
