Imidazo[1,2-a]pyridine derivatives have received great attention in recent years various fields such as pharmaceuticals and material sciences, to a lesser extent, thanks the flexibility incorporate different peripheral groups. With advance chemical synthesis routes, large number of substituted imidazo[1,2-a]pyridines been developed but are still be investigated new optical materials. Therefore, we performed spectroscopy study for set nine 3-arylthioimidazo[1,2-a]pyridine with groups reveal their structure-optical property relationships gain deeper understanding influence nature substitution. The photophysical measurements include linear absorption, fluorescence emission, quantum yield, lifetime, anisotropy solvatochromism. results showed that these properties can modulated by changing position and/or For example, yield values increase c.a. ten-fold, which is vital fluorescent applications, permanent dipole moment difference at first excited state (Δμ01) increased five-fold. Moreover, performance calculations using Density Functional Theory polarisable continuum solvation model allowed us understand electronic transitions charge transfer investigated.

ABSTRACT In this study, we have synthesized imidazo[1,2‐a] pyridine derivatives with NO ( EA 02 ) and NH 2 03 functional groups. These groups the advantage of providing sites for future branching to stabilize molecule in chosen target environment. The results obtained from our theoretical analyses (density theory, molecular orbital analysis, electrostatic potential Mulliken dynamics simulations) ADMET (absorption, distribution, metabolism, excretion toxicity) score show that are comparable lapatinib (4‐anilino‐quinazoline), an inhibitor intracellular tyrosine kinase domains epidermal growth factor receptor (EGFR). What is more, meet all Lipinski, Muegge, Egan, Veber Ghose rules drug similarity.

Developing red fluorescence emitters with simple structures via convenient synthetic routes is highly desirable yet challenging. Herein, two novel donor–acceptor-type emitters, DCFOPV-TPA and SCFOPV-TPA, featuring the intramolecular charge transfer effect were designed by integrating triphenylamine trifluoromethyl into a CN-substituted oligo(p-phenylene vinylene) backbone. Both chromophores exhibited aggregation-induced enhanced emission solvatochromic behavior. Moreover, also displayed reversible mechanofluorochromic properties under external force.
