Synthesis and characterization of a novel porphyrin derivative for optical sensor

Synthetic strategies and diversification of dibenzo[1,5]diazocines

“…Furthermore, CV analysis indicates that polymer 8b exhibited two redox couples corresponding to two reduction peaks at −0.29 and −1.23 V, and two oxidation peaks at −0.20 and −0.69 V (vs. Ag/Ag + as the internal standard). 45 In 2019, Zhang et al 46 reported the functionalisation of dibenzo [1,5]diazocine bearing two porphyrin units. Compound 2h was prepared in 27% yield from the acid-catalysed cyclisation of 2-(4-fluorobenzoyl) benzoyl azide.…”

“…This shows that the acidic and basic properties of 10 are reversible, indicating a high potential for 10 to be utilised as an optical sensor. 46 A year later, Zhang et al 47 also reported the preparation of supramolecular assemblies 10 with fullerene (C 60 ) in a solvent mixture of toluene and dichloromethane at room temperature (Scheme 3b). The UV-vis absorption spectrum of 10 in dichloromethane solution exhibits a slight hyperchromic shift centred at 420 nm and a reduction in the emission intensity in the fluorescence spectrum upon increasing the amount of C 60 .…”
