Extended π-conjugated quinazolinone derivatives with enhanced third-order nonlinear optical response

CO‐Preserving Photoinduced Transfer of Cymantrenyl Moiety: a Tandem Experimental and Computational Investigation

“…Quinazolinones are an important class of compounds with notable photophysical properties, widely used in the design of new organic materials. They find use as fluorescent probes and dyes, [11–15] molecular switches [16] and even in organic light‐emitting devices [17,18] . Owing to their commercial availability and intricate electronic structure bringing about their photochemical properties, many approaches for their functionalization were developed.…”

“…They find use as fluorescent probes and dyes, [11][12][13][14][15] molecular switches [16] and even in organic lightemitting devices. [17,18] Owing to their commercial availability and intricate electronic structure bringing about their photochemical properties, many approaches for their functionalization were developed. In particular, derivatives of quinazolinones with organometallic substituents were found to possess remarkable photo-and electrochemical properties and biological activity.…”

Synthesis, Characterization, Antibacterial, Antifungal and Anticorrosion Activities of 1,2,4-Triazolo[1,5-a]quinazolinone

“…Compounds containing nitrogen heterocycles make up a significant portion of small drug molecules that have been approved by the Food and Drug Administration (FDA), amounting to approximately 60% [ 1 ]. Numerous new nitrogen heterocycles have been synthesized for their applications in biological and material sciences [ 2 , 3 , 4 , 5 , 6 , 7 , 8 , 9 , 10 ]. Quinazoline is a frequently occurring structural feature in natural products and pharmaceutically active molecules.…”

Ultrafast broadband nonlinear optical properties and excited-state dynamics of two bis-chalcone derivatives

“…[1][2][3][4][5] It is well known that the NLO response of conjugated organic materials is closely related to the structure of the molecule, such as the size of the p-conjugated system and the introduction of electron donor and electron acceptor. [6][7][8][9][10] Hence, designing novel organic chromophores exhibiting superior NLO response is of great scientic and technological interest not only for shedding light on the nonlinear light-matter interaction but also for the development of novel photonic devices. Chalcone derivatives are a kind of pconjugated molecules and have been widely investigated in biology and medical science.…”
