“…As described in the literature, our results in this study also showed that the presence of different metals in the core of the phthalocyanine molecule can affect their inhibitory activity. This could be due to different interactions with enzymes as a result of the change in electron density of phthalocyanines (Yalazan et al, 2020;Tian et al, 2009;Arslan et al, 2020).…”

In this work, previously synthesized tetra-chalcone-substituted metallophthalocyanines (MPcs) containing Ni(II), Zn(II), Co(II), and Cu(II) in the inner core were investigated anticholinergic activities against Alzheimer's disease (AD). The MPcs were evaluated for their inhibition of acetylcholinesterase (AChE) and butyrylcholinesterase (BChE) using the original Ellman's colorimetric procedure. Against these two cholinesterase enzymes, all compounds showed inhibitory effects with IC50 values ranging from 1.243-2.369 μM against AChE and 2.865-3.372 μM against BChE. Among the four MPcs, CuPcs (2) showed the strongest inhibitory activity against AChE. ZnPcs (3) also showed the most effective inhibition for BChE.

“…In this regard, phthalocyanines containing dimethoxy groups increase solubility and can be used for various applications. 16,[26][27][28][29] Pyrazoline derivatives, which are members of heterocyclic compounds, are interesting compounds with a diverse biological profile spectrum, drug design, and synthetic versatility. The pyrazoline skeleton has been widely studied by many researchers in the field of medicinal chemistry for different diseases.…”

“…[25] These techniques make it possible to track spectral changes regarding the formation of polarons (and bipolarons), which consist of charged species produced under electrochemical conditions. [26][27][28] Herein, we present the full spectroelectrochemical study of dibenzophenazine-based emitters (Figure 1) and their polymerised products by combining UV-Vis-NIR and EPR with electrochemical analysis.…”

Previous work has reported the synthesis of donor–acceptor–donor molecules based on dibenzophenazine acceptor group, presenting thermally activated delayed fluorescent (TADF) properties and their application in the assembly of highly efficient electroluminescent devices. Herein, we focus on the characterisation of charge carrier species through UV‐Vis‐NIR spectroelectrochemical and potentiostatic EPR techniques, in addition to the investigation of electropolymerisation properties of some compounds depicted in this study. The promising electrochromic features of both small molecules and conjugated polymers led to the assembly and investigation of electrochromic devices, evidencing the materials’ versatility, applied in such different approaches as electrochromic windows and electroluminescent devices. Furthermore, the assembled OLEDs provided high efficiencies, with small roll‐off, EQEs up to 20.5 % and luminance values up to 85 000 cd/m2.
